Fourier transform technique in variational treatment of two-electron parabolic quantum dot
Sakiroglu, S.; Yildiz, A.; Dogan, Ue.; Akgungor, K.; Epik, H.; Ergun, Y.; Sari, H.; Sokmen, I. (IOP PUBLISHING LTD, 2009)In this work, we propose an efficient method of reducing the computational effort of variational calculation with a Hylleraas-like trial wavefunction. The method consists of introducing integra transforms for the terms as ... -
Ground state energy of excitons in quantum dot treated variationally via Hylleraas-like wavefunction
Sakiroglu, S.; Dogan, Ue.; Yildiz, A.; Akgungor, K.; Epik, H.; Ergun, Y.; Sari, H.; Sokmen, I. (IOP PUBLISHING LTD, 2009)In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under ... -
VARIATIONAL COMPUTATIONS FOR EXCITONS IN QUANTUM DOTS: A QUANTUM MONTE CARLO STUDY
Yildiz, A.; Sakiroglu, S.; Dogan, U.; Akgungor, K.; Epik, H.; Sokmen, I.; Sari, H.; Ergun, Y. (WORLD SCIENTIFIC PUBL CO PTE LTD, 2011)A study of variational wave functions for calculation of the ground-state energies of excitons confined in a two-dimensional (2D) disc-like and three-dimensional (3D) spherical parabolic GaAs quantum dots (QDs) is presented. ...
