Hall Resistivity and Dephasing in the Quantum Hall Insulator
Leonid P. Pryadko, Assa Auerbach
The longstanding problem of the Hall resistivity rho(x,y) in the Hall insulator phase is addressed using four-lead Chalker-Coddington networks. Electron interaction effects are int…

Quantum Magnetism Approaches to Strongly Correlated Electrons
A. Auerbach
Problems of strongly interacting electrons can be greatly simplified by reducing them to effective quantum spin models. The initial step is renormalization of the Hamiltonian into…
