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…
Entanglement properties in (1/2,1) mixed-spin Heisenberg systems
Zhe Sun, XiaoGuang Wang, AnZi Hu +1
By using the concept of negativity, we investigate entanglement in (1/2,1) mixed-spin Heisenberg systems. We obtain the analytical results of entanglement in small isotropic Heisen…
Persistent spin current in anisotropic spin ring
Yin Cheng, You-Quan Li, Bin Chen
The persistent spin current in anisotropic spin ring penetrated by a SU(2) flux is studied by the Schwinger-boson mean field approach. The anisotropy in spin coupling can facilitat…
Electron-nuclear entanglement in the cold lithium gas
Guo-Qiang Zhu, Jun-Wen Mao, You-Quan Li
We study the ground-state entanglement and thermal entanglement in the hyperfine interaction of the lithium atom. We give the relationship between the entanglement and both tempera…
Rapidly rotating Bose-Einstein condensates in an anharmonic confinement
Li-Hua Lu, You-Quan Li
We examine a rapidly rotating Bose-Einstein condensate in an anharmonic confinement and find that many properties such as the critical rotating frequency and phase diagram are quit…
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…
