Scattering matrix ensemble for time-dependent transport through a chaotic quantum dot
M L Polianski, P W Brouwer
Random matrix theory can be used to describe the transport properties of a chaotic quantum dot coupled to leads. In such a description, two approaches have been taken in the litera…
Magnetic-field dependence of energy levels in ultrasmall metal grains
S. Adam, M. L. Polianski, X. Waintal +1
We present a theory of mesoscopic fluctuations of g tensors and avoided crossing energies in a small metal grain. The model, based on random matrix theory, contains both the orbita…
Enhanced mesoscopic fluctuations in the crossover between random matrix ensembles
Shaffique Adam, Piet W. Brouwer, James P. Sethna +1
In random-matrix ensembles that interpolate between the three basic ensembles (orthogonal, unitary, and symplectic), there exist correlations between elements of the same eigenvect…
Noise through Quantum Pumps
M. L. Polianski, M. G. Vavilov, P. W. Brouwer
We study the current noise through an unbiased quantum electron pump and its mesoscopic fluctuations for arbitrary temperatures and beyond the bilinear response. In the bilinear re…
Universality of delocalization in unconventional dirty superconducting wires with broken spin-rotation symmetry
P. W. Brouwer, A. Furusaki, C. Mudry
In dirty superconducting wires, quasiparticle states at the Fermi level need not be exponentially localized if spin-rotation symmetry is broken [Brouwer {\em et al.}, Phys. Rev. Le…
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…
