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 ...

Localized magnetic fields in arbitrary directions using patterned nanomagnets
(2010)Control of the local magnetic fields desirable for spintronics and quantum information technology is not well developed. Existing methods produce either moderately small local fields or one field orientation. We present ...
