Possible existence of a band of extended states induced by inter-Landau-band mixing in quantum Hall system
Gang Xiong, Shi-Dong Wang, Qian Niu +4
The mixing of states with {\it opposite chirality} in quantum Hall system is shown to have delocalization effect. It is possible that extended states may form bands because of this…
Absence of zero-temperature transmission rate of a double-chain tight-binding model for DNA with random sequence of nucleotides in thermodynamic limit
Gang Xiong, X. R. Wang
The zero-temperature transmission rate spectrum of a double-chain tight-binding model for real DNA is calculated. It is shown that a band of extended-like states exists only for fi…
A possible minimum toy model with negative differential capacitance for self-sustained current oscillation
Gang Xiong, Z. Z. Sun, X. R. Wang
We generalize a simple model for superlattices to include the effect of differential capacitance. It is shown that the model always has a stable steady-state solution (SSS) if all…
A direct calculation of critical exponents of two-dimensional anisotropic Ising model
Gang Xiong, X. R. Wang
Using an exact solution of the one-dimensional (1D) quantum transverse-field Ising model (TFIM), we calculate the critical exponents of the two-dimensional (2D) anisotropic classic…
