Coulomb interaction and transient charging of excited states in open nanosystems
Valeriu Moldoveanu, Andrei Manolescu, Chi-Shung Tang +1
We obtain and analyze the effect of electron-electron Coulomb interaction on the time dependent current flowing through a mesoscopic system connected to biased semi-infinite leads.…
Engineered spin phase diagram of two interacting electrons in semiconductor nanowire quantum dots
Yan-Ting Chen, Shun-Jen Cheng, Chi-Shung Tang
Spin properties of two interacting electrons in a quantum dot (QD) embedded in a nanowire with controlled aspect ratio and longitudinal magnetic fields are investigated by using a…
Singlet-triplet transitions in highly correlated nanowire quantum dots
Y. T. Chen, C. C. Chao, S. Y. Huang +2
We consider a quantum dot embedded in a three-dimensional nanowire with tunable aspect ratio a. A configuration interaction theory is developed to calculate the energy spectra of t…
Coherent magnetotransport and time-dependent transport through split-gated quantum constrictions
Kristinn Torfason, Chi-Shung Tang, Vidar Gudmundsson
The authors report on modeling of transport spectroscopy in split-gate controlled quantum constrictions. A mixed momentum-coordinate representation is employed to solve a set of ti…
Time-dependent transport via the generalized master equation through a finite quantum wire with an embedded subsystem
Vidar Gudmundsson, Cosmin Gainar, Chi-Shung Tang +2
The authors apply the generalized master equation to analyze time-dependent transport through a finite quantum wire with an embedded subsystem. The parabolic quantum wire and the l…
