Effect of many-body quantum fluctuations on matrix Berry phases of a two-dimensional n-type semiconductor quantum dot
S. C. Kim, Y. J. Kim, P. S. Park +2
In the presence of spin-orbit coupling and inversion symmetry of the lateral confinement potential a single electron does not exhibit matrix Berry phases in quasi-two-dimensional s…
Polarization dependence of emission spectra of multiexcitons in self-assembled quantum dots
N. Y. Hwang, S. -R. Eric Yang
We have investigated the polarization dependence of the emission spectra of p-shell multiexcitons of a quantum dot when the single particle level spacing is larger than the charact…
Pumping in quantum dots and non-Abelian matrix Berry phases
N. Y. Hwang, S. C. Kim, P. S. Park +1
We have investigated pumping in quantum dots from the perspective of non-Abelian (matrix) Berry phases by solving the time dependent Schr{ö}dinger equation exactly for adiabatic ch…
Edge and bulk merons in double quantum dots with spontaneous interlayer phase coherence
S. -R. Eric Yang, N. Y. Hwang
We have investigated nucleation of merons in double quantum dots when a lateral distortion with a reflection symmetry is present in the confinement potential. We find that merons c…
Single electron control in n-type semiconductor quantum dots using non-Abelian holonomies generated by spin orbit coupling
S. -R. Eric Yang, N. Y. Hwang
We propose that n-type semiconductor quantum dots with the Rashba and Dresselhaus spin orbit interactions may be used for single electron manipulation through adiabatic transformat…
Hole maximum density droplets of an antidot in strong magnetic fields
N. Y. Hwang, S. -R. Eric Yang, H. -S. Sim +1
We investigate a quantum antidot in the integer quantum Hall regime (the filling factor is two) by using a Hartree-Fock approach and by transforming the electron antidot into a sys…
