Infinite bound states and hydrogen atom-like energy spectrum induced by a flat band
Yi-Cai Zhang, Guo-Bao Guo
In this work, we investigate the bound state problem in one dimensional spin-1 Dirac Hamiltonian with a flat band. It is found that, the flat band has significant effects on the bo…
Valley-Polarized Quantum Anomalous-Hall Effects in Silicene
Hui Pan, Zhenshan Li, Cheng-Cheng Liu +3
We demonstrate a new quantum state of matter---valley-polarized quantum anomalous Hall effect in monolayer silicene. In the presence of extrinsic Rashba spin-orbit coupling and exc…
Theory of orbital magnetization in disordered systems
Guobao Zhu, Shengyuan A. Yang, Cheng Fang +2
We present a general formula of the orbital magnetization of disordered systems based on the Keldysh Green's function theory in the gauge-covariant Wigner space. In our approach, t…
Luttinger liquid coupled to Bose-Einstein condensation reservoirs
Fang Cheng, Guobao Zhu, W. M. Liu +1
We investigate the transport properties for a Luttinger liquid coupled to two identical Bose-Einstein condensation reservoirs. Using the approach of equation of motion for the Gree…
