Statistical description of eigenfunctions in chaotic and weakly disordered systems beyond universality
Juan Diego Urbina, Klaus Richter
We present a semiclassical approach to eigenfunction statistics in chaotic and weakly disordered quantum systems which goes beyond Random Matrix Theory, supersymmetry techniques, a…
Andreev magnetotransport in low-dimensional proximity structures: Spin-dependent conductance enhancement
Grygoriy Tkachov, Klaus Richter
We study the excess conductance due to the superconducting proximity effect in a ballistic two-dimensional electron system subject to an in-plane magnetic field. We show that under…
Semiclassical form factor for spectral and matrix element fluctuations of multi-dimensional chaotic systems
M. Turek, D. Spehner, S. Müller +1
We present a semiclassical calculation of the generalized form factor which characterizes the fluctuations of matrix elements of the quantum operators in the eigenbasis of the Hami…
Aharonov-Bohm Physics with Spin I: Geometric Phases in One-dimensional Ballistic Rings
Martina Hentschel, Henning Schomerus, Diego Frustaglia +1
We analytically calculate the spin-dependent electronic conductance through a one-dimensional ballistic ring in the presence of an inhomogeneous magnetic field and identify signatu…
Supporting random wave models: a quantum mechanical approach
J. D. Urbina, K. Richter
We show how two-point correlation functions derived within non-isotropic random wave models are in fact quantum results that are obtained in the appropriate limit in terms of the e…
Fingerprints of mesoscopic leads in the conductance of a molecular wire
G. Cuniberti, G. Fagas, K. Richter
The influence of contacts on linear transport through a molecular wire attached to mesoscopic tubule leads is studied. It is shown that low dimensional leads, such as carbon nanotu…
