Bulk Tunneling at Integer Quantum Hall Transitions
Ziqiang Wang, Shanhui Xiong
The tunneling into the {\em bulk} of a 2D electron system (2DES) in strong magnetic field is studied near the integer quantum Hall transitions. We present a nonperturbative calcula…

Edge state transmission, duality relation and its implication to measurements
Shanhui Xiong
The duality in the Chalker-Coddington network model is examined. We are able to write down a duality relation for the edge state transmission coefficient, but only for a specific s…
