    Charge-Current Output in Plasma-Immersed Hydrogen Atom with Noncentral Interaction
    (2021) Bahar, Mustafa Kemal
    A theoretical investigation on the charge-currents and the induced magnetization of the hydrogen atom with noncentral interaction, immersed in plasma environment, under the influence of spherical encompassing is brought out. The Hartmann potential for noncentral interaction is considered, but Hartmann potential is modified because hydrogen atom is embedded in the plasma environment. The interactions in plasma are delineated by keeping in view the more general exponential cosine screened Coulomb (MGECSC) potential which reproduces more general and detailed outcomes. Shielding effect of plasma environment is regarded by modifying the Hartmann potential through the MGECSC potential. Thus, hydrogen atom is considered to be under the influence of the plasma modified Hartmann (PMH) potential. While the numerical tridiagonal matrix method (TMM) is employed due to the difficulty of analytical solution to the radial wave equation in nonrelativistic scheme including PMH potential, a hybrid solution technique is preferred by using the asymptotic iteration method (AIM) to solve the angular wave equation. The present work demonstrates an elaborative analysis on generation and control of the charge-currents and the induced magnetization of the plasma shielding effect, the spherical encompassing effect, and noncentral effect. In this analysis, the altenativeness to each other of the plasma environment, the spherical encompassing and the noncentral effect is also evaluated, and suggestions are made for related application studies.

    Combined effects of thermodynamic factors and external fields for nonlinear optical processes of deformed Mathieu quantum dot containing central impurity
    (Elsevier, 2023) Bahar, Mustafa Kemal; Baser, Pinar
    The theoretical impact of external parameters such as the hydrostatic pressure, temperature, electric field, magnetic field, as well as the Indium (In) concentration and quantum dot width on the nonlinear optical properties of a Mathieu quantum dot (MQD) with a screw dislocation and a hydrogenic impurity at its center, formed by an InxGa1-xAs/GaAs heterojunction, is presented. The wave equation of the system is solved in cylindrical coordinates using the effective mass approximation and the Runge-Kutta-Fehlberg (RKF) method, taking into account the direction of the screw dislocation and the symmetry of the structure. In addition to the screw dislocation, thermodynamic effects, electric and magnetic fields, In concentration, and the width of the MQD have significant effects on the electronic energy levels, dipole matrix elements, and transition frequencies, resulting in important consequences for the nonlinear optical properties. The effects and alternatives of the relevant parameters on the nonlinear optical properties of the MQD with a screw dislocation are discussed in detail. The optical properties that can be altered by these parameters may also be important for experimental studies in determining the optimality of the structure.& COPY; 2023 Elsevier B.V.

    Exploring the dynamics of H atom guested endofullerene embedded in plasma with ultrashort chirped laser pulses
    (World Scientific Publ Co Pte Ltd, 2024) Bahar, Mustafa Kemal
    In this work, the effects of an ultrashort laser pulse on the excitation and ionization dynamics of a hydrogen guested endofullerene system embedded in a quantum plasma environment under spherical encompassment are investigated. The interaction of the plasma environment is considered within the more general exponential cosine screened Coulomb (MGECSC) potential model, and the excitation and ionization dynamics are analyzed through plasma screening parameters. For endohedral confinement, the relevant model that aligns with experimental data and is most suitable for static endohedral encapsulation is the Woods-Saxon potential model. By considering different numerical ranges of the parameters in this model, the effects of various forms of fullerenes are thoroughly explained through the analysis of confinement depth, spherical shell thickness, inner radius and the smoothing parameters. The effects of the characteristic properties of the laser pulse, such as its intensity and frequency, on the probability dynamics are also discussed. All parameters and their respective ranges are important for optimizing system performance. Additionally, the alternatives of all parameters related to the plasma-embedded endofullerene system for probability dynamics are considered. In this context, the findings cause new ideas in the controlled excitation and ionization processes of endofullerene systems embedded in a quantum plasma environment and provide a significant foundation for future experimental studies.

    Li @ C n immersed in nonideal classical plasmas
    (Springer Science and Business Media Deutschland GmbH, 2022) Bahar, Mustafa Kemal
    The present work considers an endohedrally encapsulated guest Li atom immersed in a nonideal classical plasma under a spherical encompassment. In this combined system, the Woods–Saxon potential is used as the model for endohedral fullerene (EF), while the model potential approach is employed for the Li atom. The relevant wave equation is solved by the tridiagonal matrix method. The energy states, oscillator strengths, dipole polarizabilities, orbital charge-currents and induced magnetic fields of the Li @ C n system are examined in detail for both structural effects and plasma shielding effects. The combined system under consideration and the corresponding investigations have never been reported in the literature before. Various types of EFs can be synthesized experimentally. However, considering the fact that experimental production is still in its infancy, the necessity of a great number of theoretical studies becomes clearer. The most important expectation in this work is to establish a tuning mechanism thanks to elucidating the effect of the structural specifications of EFs on the mentioned atomic properties as well as the functionality of the plasma shielding effect, which we believe is provided. All parameter values in this work are experimentally achievable. Both special data values and data ranges, which causes remarkable features for the system, are determined. By examining these data, the alternatives of the parameters to each other for the purpose-oriented functions are also analyzed. © 2022, The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature.

    Magneto-optical specifications of Rosen-Morse quantum dot with screw dislocation
    (Wiley, 2020) Bahar, Mustafa Kemal; Ungan, Fatih
    This is the first study to consider a quantum dot with screw dislocation that has Rosen-Morse (RM) confinement potential, generated by a GaAs/GaAlAs heterostructure. An external magnetic field and Aharonov-Bohm (AB) flux field were also applied on RM quantum dot (RMQD) in order to stave the effects of a screw dislocation defect. The combined effect of the screw dislocation defect, the external magnetic field, and AB flux field on the total refractive index changes (TRICs) and the total absorption coefficients (TACs) of RMQD are thus investigated. Cylindrical coordinates are used due to the direction of application of the torsion and the external fields, as well as due to the structure's symmetry. The effective mass approximation and tridiagonal matrix methods are used in order to obtain the subband energy spectra and electronic wave functions of RMQD. The nonlinear optical specifications of RMQD are checked using compact-density-matrix formalism within the framework of the iterative method. Reviews without screw dislocation are also carried out in order to be able to clarify the effects of a screw dislocation defect on the optical properties, and then, both cases are deliberated. This study is the first attempt to analyze the AB flux field for RMQD without screw dislocation. In the present study, the influences of a screw dislocation defect on RMQD's TRICs and TACs are probed by considering different values of the external magnetic field and AB flux field, and the ranges of corresponding parameters on the optimum of the structure are specified. Moreover, the study also elucidates how to rule out the effects of screw dislocation on optical specifications by means of the external fields. Despite a certain screw dislocation, the frequency range is determined where the structure behaves as if it is perfect (namely, without screw dislocation) for its optimum, which in turn is crucial for experimental applications.

    Nonlinear optical specifications of the Mathieu quantum dot with screw dislocation
    (Springer Heidelberg, 2023) Bahar, Mustafa Kemal; Baser, Pinar
    In this study, the nonlinear optical properties of screw dislocation Inx Ga1-x As/GaAs Mathieu quantum dots (MQDs) are theoretically investigated for the first time, focusing on the optical rectification (NOR), second harmonic generation (SHG), and third harmonic generation (THG). In addition to the screw dislocation in the structure, external electric and magnetic fields, as well as the Aharonov-Bohm (AB) flux, are applied to the system. The aim of the study is to interpret how the characteristics of the NOR, SHG, and THG of MQDs change depending on the screw dislocation defect, external fields, AB flux, and structural factors such as indium concentration (In) and quantum dot width. The wave equation of the system is solved using the effective mass approximation and the Runge-Kutta-Fehlberg method in cylindrical coordinates, taking into account the direction of twist and the symmetry of the structure. The influence of all parameters on the nonlinear optical properties of the MQD with screw dislocation and their alternatives are discussed in detail. Furthermore, the optimality of the structure is discussed for a certain amount of screw dislocation, which can be important for experimental applications and device designs.

    Optical response of plasma processed quantum dot under the external fields
    (Wiley, 2021) Kilic, Kadir; Bahar, Mustafa Kemal
    We investigate theoretically the total refractive index changes (TRICs) and the total absorption coefficients (TACs) of two-electron Gaussian quantum dot (TEGQD) including Gaussian potential confinement generated by GaAs/GaAlAs heterostructure, embedded in Debye and quantum plasma environments modeled by the more general exponential cosine screened Coulomb (MGECSC) potential, under the influence of the external electric and magnetic field. The wave equation is solved within the effective mass approach framework by using Runge-Kutta-Fehlberg method in order to obtain the subband spectra and the electronic wave functions of TEGQD. Nonlinear optical response of TEGQD is obtained through the compact-density-matrix formalism within the iterative method. The effects of both Debye and quantum plasma environments in the strong and weak regimes of the external fields are considered and compared throughout the study. The potents of the external electric field, the external magnetic field, the quantum dot width, the barrier height, and the plasma screening on TRICs and TACs resonant frequencies and amplitudes are analyzed. In addition to these analyses, the alternatives to each parameter effects of the model are also elucidated. TRICs and TACs analyze are carried out in a plasma-free environment, and thus the function of environments with plasma compared to that without plasma is better explained. Thanks to all these reviews, it is elucidated how to and at what ranges perform in terms of the incident photon energy of TEGQD's optimum for TRICs and TACs characters by using plasma, and in which cases it will be an alternative to the external field and geometrical encompassing.

    Persistent currents of ultrarelativistic plasma-encased endofullerene molecules entrapping a H atom
    (Iop Publishing Ltd, 2024) Bahar, Mustafa Kemal
    In this work, for the first time in the relevant literature, the persistent currents (PC) and induced magnetic fields (IMF) of an endofullerene molecule entrapping a hydrogen atom, under spherical confinement, are investigated. The endofullerene molecule is enclosed within a spherical region and embedded in a plasma environment. The plasma environment is depicted with the more general exponential cosine screened Coulomb potential, and its relevant effects are analyzed by considering plasma screening parameters. The relevant model for endohedral confinement is the Woods-Saxon confinement potential, which is compatible with experimental data. The effects of various forms of C n are thoroughly elucidated via the analysis of the confinement depth, spherical shell thickness, the inner radius, and the smoothing parameters. To find the bound states in the spherically confined endofullerene, the decoupling of the second-order Dirac equation for the large and small components of the radial atomic wave functions is considered. The Dirac equation with the interaction potential is solved numerically by using the Runge-Kutta-Fehlberg method via the decoupling formalism. The influence of spin orientations on the PC and IMF is also elucidated. The effects of spherical confinement, plasma shielding, and the structural properties of the fullerene on the PC and IMF are thoroughly viewed. Moreover, under given physical conditions, the optimal ranges of these effects are determined.

    Photoionization Cross Section for H@Cn${\text{H@C}}_{n}$ Implanted in Nonideal Classical Plasmas
    (Wiley-V C H Verlag Gmbh, 2023) Bahar, Mustafa Kemal; Martinez-Flores, Cesar
    In this study, photoionization cross sections of guest hydrogen atom in endohedral fullerene (H@Cn${\text{H@C}}_{n}$) modeled by the Woods-Saxon confinement potential implanted in the nonideal classical plasma (NICP) under spherical confinement are reported for the first time in the related literature. The relevant wave equation is solved numerically via the tridiagonal matrix method and then the energy levels, bound and continuum wave functions are interpreted. Plasma effect is examined by considering plasma temperature and density and is evaluated in the photoionization process. Since the plasma modifies the discrete and continuum spectra by changing the potential energy of hydrogen atom, it closely affects the overlapping of the wave functions of ground state and continuum state. This effect has a distinct response on photoionization resonances. Using different values of endohedral confinement parameters, which means regarding different types of fullerenes, detailed analysis of energy levels, bound and continuum wave functions, and photoionization cross sections are provided by evaluating confinement width, depth, smoothing effect and distance from the spherical encompassement center. The photoionization process of H@Cn${\text{H@C}}_{n}$ implanted in the NICP (nonideal classical plasma) is highly sensitive to both plasma and endohedral confinement. At this sensitivity, Cooper resonance character is like an encoder for fullerene structure.

    Photoionization process of energy-dependent excited He atom trapped inside endofullerene molecules encased in a quantum plasma
    (Springer, 2024) Bahar, Mustafa Kemal
    We consider the excited He atom 1s2s(1)S (He*@C-n) trapped within an energy-dependent endohedral fullerene, encased in a quantum plasma described by the more general exponential cosine screened Coulomb (MGECSC) potential, under a spherical confinement. The nonrelativistic wave equation is solved using the Runge-Kutta-Fehlberg (RKF) method, and discrete and continuum spectra along with the corresponding wave functions are obtained. The screening effect of the plasma medium, endohedral trapping, and the shifted effect due to energy-dependence modify the effective potential energy of the system, influencing the localization of discrete and continuum states and leading to various overlapping scenarios. The new localizations, various overlapping cases, and interference of outgoing and scattering photoelectron waves lead to explicit confinement resonances. Considering these resonances, peaks in the photoionization cross sections (PCSs) are analyzed. This analysis provides significant details for the photoionization dynamics of the artificial system He*@C-n. The relevant ranges and critical values of plasma, endohedral encapsulation, and energy dependence parameters in the process of formation of these resonances and during PCS investigations are explained. Additionally, the cross section curves, resonance positions, effective photoelectron energy range, and overall PCS behaviors are described. This information can be important for potential experiments, in addition to other theoretical investigations. This information can be crucial not only for further theoretical investigations but also for potential experiments.

    Photoionization treatment of encompassed plasma-implanted exotic atoms
    (Springer Heidelberg, 2024) Bahar, Mustafa Kemal
    This work chews over exotic systems embedded in a non-ideal classical plasma (NICP) under impenetrable spherical confinement, including mu H, (mu He)(+), and (mu Li)(++) systems within a nonrelativistic formalism. The photoionization processes of exotic atomic systems are thoroughly analyzed for different values of the NICP's plasma screening parameter, hence plasma temperature and density, and the radius of spherical confinement. In each case, the energy levels of exotic systems are shown and interpreted in terms of their characteristics. The heavy nature of the muon significantly influences the entire process. Additionally, observable outcomes of different attraction effects originating from the nucleus in muonic systems on both the spectrum and photoionization are identified. The short lifetimes of relevant exotic systems due to the muon and the high bound state energies resulting from the strong attraction energy of the muon significantly inconvenience the photoionization process. However, these disadvantages can be overcome thanks to NICP and spherical confinement, thereby facilitating experimental applications. Important findings regarding these facilitation processes are presented in the present work.

    Plasma-embedded positronium atom with energy-dependent potential
    (2021) Bahar, Mustafa Kemal
    In this study, for the first time in the related literature, the positronium atom embedded in the plasma environment with energy-dependent potential interaction, under spherical confinement, is investigated. The more general exponential cosine-screened Coulomb (MGECSC) potential is used to describe the interaction potential of the positronium atom in the plasma environment.Amongfour different sets ofMGECSCpotential tomodelDebye and quantum plasma, the most general form for calculations is considered, and thus, the positronium atom investigated contained energy-dependent potential interaction embedded in the quantum plasma environment. The energy dependence of the interaction potential is chosen linearly and rendered to a tunable case by using a dimensionless parameter.MGECSC potential is modified by considering the linear energy dependence. The nonrelativistic spectrum and wave functions of the energy-dependent MGECSC potential (energy-dependent plasma (EDP) potential) for the positronium atom are obtained using the Runge–Kutta–Fehlberg (RKF) method. The effect of the plasma shielding parameters, the spherical encompassing effect and the energy dependence on generation and control of the orbital charge-currents and the induced magnetic fields of the positronium atom are examined. Furthermore, the transition energies, the oscillator strengths and the dipole polarizability are studied for only energy dependence. For the energy-independent case, the structural property review is also performed, and the results are compared. Alternatives to each other of the effective potential parameters on the charge-currents, the induced magnetic fields and the structural properties are also discussed. The charge-current and induced magnetic field analyses are also performed for energy-dependent potential-plasma environment case, plasma environmentenergy- independent potential case, no-plasma environment-energy-dependent potential case, and no-plasma environment-energy-independent potential case.

    Radiative dynamics of laser-driven Li@Cn embedded in quantum plasma
    (Iop Publishing Ltd, 2024) Bahar, Mustafa Kemal
    This work considers a guest Lithium atom (Li@C-n ) in an endohedral fullerene, embedded in a quantum plasma modeled by the more general exponential cosine screened Coulomb (MGECSC) potential, under the influence of a spherical confinement and laser radiation field. The system is examined in nonrelativistic form and the related wave equation is solved using the tridiagonal matrix method (TMM), thus obtaining the discrete-continuum spectrum and related wave functions. The numerical values of the relevant parameters in this process are physically accessible values. The effects of the plasma, laser field and endohedral cavity on the photoionization cross section (PCS) are analysed in detail. The shielding effect of the plasma medium and the pulsating effect of the laser field modify the effective potential energy of the system, affecting the localizations of the 2s and continuum states, causing various overlapping cases. Considering different values of the endohedral encompassement parameters, which means that different types of fullerenes are taken into account, overlapping cases occur for different spectra and wave functions. Scrutinising these overlappings, the confinement and Cooper resonances of the PCSs are analysed. This analysis provides many details for the radiative dynamics of an artificial system Li@C-n . The relevant ranges and critical values of plasma, laser field, and endohedral encapsulation parameters in the formation process of these resonances and PCSs are explained, as well as the cross-section curves, resonance positions, effective photoelectron energy range, and general PCS behavior, which can be important for potential experiments in addition to other theoretical investigations.

    Short laser pulse effects on spectral dynamics of encapsulated He, Ne, Ar atoms in fullerenes
    (Springer, 2024) Bahar, Mustafa Kemal
    This work elucidates the effects of a short laser pulse on the excitation and ionization dynamics of an endofullerene system trapping He, Ne, and Ar atoms. The interactions of noble gas atoms are simulated within the framework of the Single Active Electron (SAE) approximation, and the encapsulation parameters are analyzed to illustrate the excitation and ionization dynamics. The endohedral confinement is modeled using the Woods-Saxon potential, which is a practical and advantageous model that aligns well with experimental data and considers static encapsulation. By considering different numerical values of the endohedral trapping parameters in simulating encapsulation, a detailed analysis on the depth of confinement, spherical shell thickness, the inner radius, and the smoothing parameters is performed to ferret out encapsulation effects in various forms. By determining the strength range and specific frequency values (and ranges) of the laser pulse, the work interprets how electron dynamics in endohedral fullerenes are shaped under laser pulses. All parameters and their respective ranges are crucial gains for optimizing system performance.

    The second, third harmonic generations and nonlinear optical rectification of the Mathieu quantum dot with the external electric, magnetic and laser field
    (Elsevier, 2023) Bahar, Mustafa Kemal; Baser, Pinar
    In this study, the nonlinear optical properties of the In ������Ga1-������As/GaAs Mathieu quantum dot (MQD) are investigated for the first time, focusing on the nonlinear optical rectification (NOR), second harmonic generation (SHG), and third harmonic generation (THG). The effects of external fields such as the electric field, magnetic field, and laser radiation field on the nonlinear optical properties of MQD are examined, along with structural parameters such as quantum dot depth and width determined by the indium concentration. The motivation of the study is to explain the NOR, SHG, and THG characteristics of MQD in response to changes in external fields and structural factors. To investigate the effects of the laser field, the time-dependent part of the laser field is transferred to the potential energy term of the wave equation using the Kramers-Henneberger (KH) and dipole approximations, creating a laser-dressed potential. Then, the effective potential wave equation is solved using the tridiagonal matrix method. The effects of external fields and structural parameters of MQD on the NOR, SHG, and THG coefficients are discussed in detail. The optimality of the structure for device design and applications considering MQD is revealed, and alternative parameter analysis is conducted for this optimality.

    Velocity-dependent potential effects on two interacting electrons in Cornell quantum dot planted in plasma medium
    (Sivas Cumhuriyet Üniversitesi, 2021) Bahar, Mustafa Kemal
    In this study, the energy levels of two-electron Cornell quantum dot (TECQD) immersed in Debye and quantum plasma mediums are probed. To model plasma mediums, the more general exponential cosine screened Coulomb (MGECSC) is suggested. The presence of TECQD in plasma environment and velocity-dependent potential (VDP) effect in the system render very difficult to solve the relevant wave equation. Since the analytical solution of the relevant wave equation is very difficult, the numerical asymptotic iteration method (AIM) is used. As well as the effects of the encompassing parameters on the energy levels and possible radiations of TECQD, the effects of VDP and quantum (and Debye) plasma medium are also presented in detail. In addition, the alternativeness of VDP, quantum (and Debye) plasma and encompassing parameters to each other on these effects are also discussed.
