Nonlinear Transport of Bose-Einstein Condensates Through Waveguides with Disorder
Tobias Paul, Patricio Leboeuf, Nicolas Pavloff +2
We study the coherent flow of a guided Bose-Einstein condensate incident over a disordered region of length L. We introduce a model of disordered potential that originates from mag…
Semiclassical theory of weak antilocalization and spin relaxation in ballistic quantum dots
Oleg Zaitsev, Diego Frustaglia, Klaus Richter
We develop a semiclassical theory for spin-dependent quantum transport in ballistic quantum dots. The theory is based on the semiclassical Landauer formula, that we generalize to i…
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…
Thermopower of a superconducting single-electron transistor
M. Turek, J. Siewert, K. Richter
We present a linear-response theory for the thermopower of a single-electron transistor consisting of a superconducting island weakly coupled to two normal-conducting leads (NSN SE…
Geometrical enhancement of the proximity effect in quantum wires with extended superconducting tunnel contacts
Giorgos Fagas, Grigory Tkachov, Andreas Pfund +1
We study Andreev reflection in a ballistic one-dimensional channel coupled in parallel to a superconductor via a tunnel barrier of finite length . The dependence of the low-ener…
