Competing broken-symmetry and rotationally symmetric spin-singlet states in a few-electron quantum dot in a magnetic field
(2008)On the basis of developed variational many-body approach, within a second quantized formulation, the nature of the ground state of a few-electron system in a parabolic two-dimensional (2D) quantum dot (QD) is theoretically ...

Exciton-donor complexes in semiconductor quantum dots in a magnetic field: Infinite and finite potential barriers
(2008)The binding energy of the ground state of a charged exciton-donor complex in a spherical semiconductor quantum dot with infinite and finite potential barriers as well as the oscillator strength for the optical transition ...
