Nucleation of ergodicity by a single mobile impurity in supercooled insulators
Ulrich Krause, Théo Pellegrin, Piet W. Brouwer +2
We consider a disordered Hubbard model, and show that, at sufficiently weak disorder, a single spin-down mobile impurity can thermalize an extensive initially localized system of s…
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…
Photonic excess noise and wave localization
C. W. J. Beenakker, M. Patra, P. W. Brouwer
This is a theory for the effect of localization on the super-Poissonian noise of radiation propagating through an absorbing disordered waveguide. Localization suppresses both the m…
High-frequency dynamics of wave localisation
C. W. J. Beenakker, K. J. H. van Bemmel, P. W. Brouwer
We study the effect of localisation on the propagation of a pulse through a multi-mode disordered waveguide. The correlator <u(omega1)u*(omega2)> of the transmitted wave amplitude…
Distribution of the reflection eigenvalues of a weakly absorbing chaotic cavity
C. W. J. Beenakker, P. W. Brouwer
The scattering-matrix product SS+ of a weakly absorbing medium is related by a unitary transformation to the time-delay matrix without absorption. It follows from this relationship…
The random magnetic flux problem in a quantum wire
Christopher Mudry, P. W. Brouwer, Akira Furusaki
The random magnetic flux problem on a lattice and in a quasi one-dimensional (wire) geometry is studied both analytically and numerically. The first two moments of the conductance…
