The numerical operator method to the real time dynamics of currents through the nanostructures with different topologies
Pei Wang, Xuean Zhao, Ling Tang
We present the numerical operator method designed for the real time dynamics of currents through nanostructures beyond the linear response regime. We apply this method to the trans…
Spin precession caused by spin-spin interaction between bounded electrons in quantum dots
Pei Wang, Jin-liang Zheng, Xuean Zhao
In this paper, we study the spin-spin interaction between two electrons bounded in a quantum dot. The result shows that spin-spin interaction will cause a pair of spins precessing…
Nonvanishing spin Hall currents in the presence of magnetic impurities
Pei Wang, You-Quan Li, Xuean Zhao
The intrinsic spin Hall conductivity in a two dimensional electron gas with Rashba spin-orbit coupling is evaluated by taking account of anisotropic coupling between magnetic impur…
Correlations of spin-polarized and entangled electrons with Berry phase
Xuean Zhao, Hui Zhao, Pei Wang +1
The correlation and fluctuation of both entangled electrons and spin-polarized pairs affected by two rotating magnetic fields in a setup proposed by J. Carlos Egues etc. (Phys. Rev…
Spin-flip process through a quantum dot coupled to ferromagnetic electrodes
Huanwen Lai, Xuean Zhao, Zhu-An Xu +1
We study the spin-dependent transport through a quantum dot coupled to two ferromagnetic electrodes using the equation of motion method for the nonequilibrium Green's functions. Ou…
Shot Noise for Entangled Electrons with Berry Phase
Hui Zhao, Xuean Zhao, You-Quan Li
We study shot noise for entangled electrons in a 4-lead beam-splitter with one incoming lead driven by adiabatically rotating magnetic fields. We propose a setup of an adiabaticall…
