Zero-modes in the random hopping model
P. W. Brouwer, E. Racine, A. Furusaki +3
If the number of lattice sites is odd, a quantum particle hopping on a bipartite lattice with random hopping between the two sublattices only is guaranteed to have an eigenstate at…
Transport Properties and Density of States of Quantum Wires with Off-diagonal Disorder
P. W. Brouwer, C. Mudry, A. Furusaki
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 co…
Nonuniversality in quantum wires with off-diagonal disorder: a geometric point of view
P. W. Brouwer, C. Mudry, A. Furusaki
It is shown that, in the scaling regime, transport properties of quantum wires with off-diagonal disorder are described by a family of scaling equations that depend on two paramete…
Density of states in coupled chains with off-diagonal disorder
P. W. Brouwer, C. Mudry, A. Furusaki
We compute the density of states (d.o.s.) in N coupled chains with random hopping. At zero energy, the d.o.s. shows a singularity that strongly depends on the parity of N. For odd…
Anderson localization due to random magnetic field in two dimensions
A. Furusaki
Results of large-scale numerical simulations are reported on the Anderson localization in a two-dimensional square lattice tight-binding model with random flux. Localization length…
Dynamical spin correlations in Heisenberg ladder under magnetic field and correlation functions in SO(5) ladder
A. Furusaki, S. C. Zhang
The zero-temperature dynamical spin-spin correlation functions are calculated for the spin-1/2 two-leg Heisenberg ladder in a magnetic field above the lower critical field Hc1. The…
