Transport Properties and Density of States of Quantum Wires with Off-diagonal Disorder
P. W. Brouwer, C. Mudry, A. Furusaki
Abstract
We review recent work on the random hopping problem in a quasi-one-dimensional geometry of N coupled chains (quantum wire with off-diagonal disorder). Both density of states and conductance show a remarkable dependence on the parity of N. The theory is compared to numerical simulations.
