Quantum Spinon Oscillations
Zi Cai, Lei Wang, X. C. Xie +4
The full quantum dynamics of a spinon under external magnetic fields is investigated by using the time-evolving block decimation (TEBD) method within the microcanonical picture of…
Interaction-induced anomalous transport behavior in one dimensional optical lattice
Zi Cai, Lei Wang, X. C. Xie +1
The non-equilibrium dynamics of spin impurity atoms in a strongly interacting one-dimensional (1D) Bose gas under the gravity field is studied. We show that due to the non-equilibr…
Quantum size effects in thermodynamic superconducting properties of ultra thin films
Bin Chen, Zhenyue Zhu, X. C. Xie
By using multi-bands BCS theory, we have calculated the superconductivity energy gap and the critical temperature of a thin-film metallic superconductor. The thermodynamic supercon…
Resonant spin Hall conductance in quantum Hall systems lacking bulk and structural inversion symmetry
Shun-Qing Shen, Yun-Juan Bao, Michael Ma +2
Following a previous work [Shen, Ma, Xie and Zhang, Phys. Rev. Lett. 92, 256603 (2004)] on the resonant spin Hall effect, we present detailed calculations of the spin Hall conducta…
Theory for high spin systems with orbital degeneracy
Shun-Qing Shen, X. C. Xie, F. C. Zhang
High-spin systems with orbital degeneracy are studied in the large spin limit. In the absence of Hund's coupling, the classical spin model is mapped onto disconnected orbital syste…
Pseudospin SU(2) Symmetry Breaking, Charge Density Wave and Superconductivity in the Hubbard Model
S. Q. Shen, X. C. Xie
In this paper, we discuss physical consequences of pseudospin SU(2) symmetry breaking in the negative-U Hubbard model at half-filling. If pseudospin symmetry is spontaneously broke…
