Quantum correlations in spin models
Guo-Feng Zhang, Heng Fan, Ai-Ling Ji +3
Bell nonlocality, entanglement and nonclassical correlations are different aspects of quantum correlations for a given state. There are many methods to measure nonclassical correla…
Measurement-induced disturbance and thermal entanglement in spin models
Guo-Feng Zhang, Zhao-Tan Jiang, Ahmad Abliz
Quantum correlation in two-qubit spin models is investigated by use of measurement-induced disturbance [S. Luo, Phys. Rev. A, 77(2008) 022301]. Its dependences on external magnetic…
Spin superconductor in ferromagnetic graphene
Qing-feng Sun, Zhao-tan Jiang, Yue Yu +1
We show a spin superconductor (SSC) in ferromagnetic graphene as the counterpart to the charge superconductor, in which a spin-polarized electron-hole pair plays the role of the sp…
Do intradot electron-electron interactions induce dephasing?
Zhao-tan Jiang, Qing-feng Sun, X. C. Xie +1
We investigate the degree of coherence of electronic transport through a quantum dot (QD) in the presence of an intradot electron-electron interaction. By using an open multi-termi…
