An ergodic theorem for Delone dynamical systems and existence of the integrated density of states
Daniel Lenz, Peter Stollmann
We study strictly ergodic Delone dynamical systems and prove an ergodic theorem for Banach space valued functions on the associated set of pattern classes. As an application, we pr…
Anisotropic Quantum Hall Matrix Model
Ahmed Jellal, Rudolf A. Roemer, Michael Schreiber
We consider the anisotropic effect in the quantum Hall systems by applying a confining potential that is not of parabolic type. This can be done by extending Susskind--Polychronako…
Fluctuating Hall resistance defeats the quantized Hall insulator
Philipp Cain, Rudolf A. Roemer
Using the Chalker-Coddington network model as a drastically simplified, but universal model of integer quantum Hall physics, we investigate the plateau-to-insulator transition at s…
Stochastic unraveling of Redfield master equations and its application to electron transfer problems
Ivan Kondov, Ulrich Kleinekathoefer, Michael Schreiber
A method for stochastic unraveling of general time-local quantum master equations (QMEs) is proposed. The present kind of jump algorithm allows a numerically efficient treatment of…
On the Determinant of a Certain Wiener-Hopf + Hankel Operator
Estelle L. Basor, Torsten Ehrhardt, Harold Widom
We establish an asymptotic formula for determinants of truncated Wiener-Hopf+Hankel operators with symbol equal to the exponential of a constant times the characteristic function o…
Self-stabilization of high frequency oscillations in semiconductor superlattices by time-delay autosynchronization
J. Schlesner, A. Amann, N. B. Janson +2
We present a novel scheme to stabilize high-frequency domain oscillations in semiconductor superlattices by a time-delayed feedback loop. Applying concepts from chaos control theor…
