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…
Entanglement of degenerate ground state for spin 1 and 1/2 pair
You-Quan Li, Guo-Qiang Zhu, Xue-An Zhao
We study the entanglement feature of the ground state of a system composed of spin 1 and 1/2 parts. The concurrence vector is shown to be consistent with the measurement of von Neu…
