Decreasing excitation gap in Andreev billiards by disorder scattering
Florian Libisch, Jürgen Möller, Stefan Rotter +2
We investigate the distribution of the lowest-lying energy states in a disordered Andreev billiard by solving the Bogoliubov-de Gennes equation numerically. Contrary to conventiona…
Diffractive paths for weak localization in quantum billiards
Iva Brezinova, Christoph Stampfer, Ludger Wirtz +2
We study the weak localization effect in quantum transport through a clean ballistic cavity with regular classical dynamics. We address the question which paths account for the sup…
Staggered repulsion of transmission eigenvalues in symmetric open mesoscopic systems
Marten Kopp, Henning Schomerus, Stefan Rotter
Quantum systems with discrete symmetries can usually be desymmetrized, but this strategy fails when considering transport in open systems with a symmetry that maps different openin…
Statistics of Transmission Eigenvalues in Two-Dimensional Quantum Cavities: Ballistic versus Stochastic Scattering
Stefan Rotter, Florian Aigner, Joachim Burgdörfer
We investigate the statistical distribution of transmission eigenvalues in phase-coherent transport through quantum dots. In two-dimensional ab-initio simulations for both clean an…
Simulation of Electron Transport through a Quantum Dot with Soft Walls
Bernhard Weingartner, Stefan Rotter, Joachim Burgdoerfer
We numerically investigate classical and quantum transport through a soft-wall cavity with mixed dynamics. Remarkable differences to hard-wall quantum dots are found which are, in…
Pseudo-Path Semiclassical Approximation to Transport through Open Quantum Billiards: Dyson Equation for Diffractive Scattering
C. Stampfer, L. Wirtz, S. Rotter +1
We present a semiclassical theory for transport through open billiards of arbitrary convex shape that includes diffractively scattered paths at the lead openings. Starting from a D…
