Negative electronic compressibility enables electrically-induced charge density waves in a two-dimensional electron liquid
Erica E. Hroblak, Alessandro Principi, Hui Zhao +1
We show that the negative electronic compressibility of two-dimensional electronic systems at sufficiently low density enables the generation of charge density waves through the ap…
Energy spread and current-current correlation in quantum systems
Yonghong Yan, Feng Jiang, Hui Zhao
We consider energy (heat) transport in quantum systems, and establish a relationship between energy spread and energy current-current correlation function. The energy current-curre…
Ambipolar spin diffusion and D'yakonov-Perel' spin relaxation in GaAs quantum wells
Hui Zhao, Matt Mower, G. Vignale
We report theoretical and experimental studies of ambipolar spin diffusion in a semiconductor. A circularly polarized laser pulse is used to excite spin-polarized carriers in a GaA…
Controllable spin-current blockade in a Hubbard chain
Yao Yao, Hui Zhao, Joel E. Moore +1
We investigate the spin/charge transport in a one-dimensional strongly correlated system by using the adaptive time-dependent density-matrix renormalization group method. The model…
Temperature dependence of ambipolar diffusion in silicon-on-insulator
Hui Zhao
Spatiotemporal dynamics of electron-hole pairs locally excited in a silicon-on-insulator structure by indirect interband absorption are studied by measuring differential transmissi…
Phonon Effects on Spin-Charge Separation in One Dimension
W. Q. Ning, Hui Zhao, C. Q. Wu +1
Phonon effects on spin-charge separation in one dimension are investigated through the calculation of one-electron spectral functions in terms of the recently developed cluster per…
