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…
Generation and detection of non-Abelian matrix Berry phases through manipulation of electric confinement potential of a semiconductor quantum dot
S. -R. Eric Yang, N. Y. Hwang
A matrix Berry phase can be generated and detected by {\it all electric means} in II-VI or III-V n-type semiconductor quantum dots by changing the shape of the confinement potentia…
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…
