A metallic phase in quantum Hall systems
Gang Xiong, Shi-Dong Wang, Qian Niu +2
The electronic eigenstates of a quantum Hall (QH) system are chiral states. Strong inter-Landau-band mixings among these states can occur when the bandwidth is comparable to the sp…

Transition from Integer Quantum Hall State to Insulator
X. C. Xie, D. Z. Liu
We study disorder induced transition between quantum Hall states and insulator state in a {\it lattice} model. We find the positions of the extended states do not change as disorde…

Weak Field Phase Diagram for an Integer Quantum Hall Liquid
D. Z. Liu, X. C. Xie, Q. Niu
We study the localization properties in the transition from a two-dimensional electron gas at zero magnetic field into an integer quantum Hall (QH) liquid. By carrying out a direct…
