Fourier transform technique in variational treatment of two-electron parabolic quantum dot

Şakiroğlu, S.; Yıldız, A.; Doğan, Ue.; Akgüngor, K.; Epik, H.; Ergün, Y.; Sökmen, 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

Şakiroğlu, S.; Doğan, Ue.; Yıldız, Aylin; Akgüngor, K.; Epik, H.; Ergün, Yüksel; Sökmen, 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

Yıldız, A.; Şakiroğlu, S.; Doğan, U.; Akgüngor, K.; Epik, H.; Sökmen, I.; Ergün, Yüksel (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. ...
