Universal dephasing rate due to diluted Kondo impurities
T. Micklitz, A. Altland, T. A. Costi +1
We calculate the dephasing rate due to magnetic impurities in a weakly disordered metal as measured in a weak localization experiment. If the density n_S of magnetic impurities is…
Periodic-Orbit Theory of Universality in Quantum Chaos
Sebastian Müller, Stefan Heusler, Petr Braun +2
We argue semiclassically, on the basis of Gutzwiller's periodic-orbit theory, that full classical chaos is paralleled by quantum energy spectra with universal spectral statistics,…
Field Theory Approach to Quantum Interference in Chaotic Systems
Jan Müller, Alexander Altland
We consider the spectral correlations of clean globally hyperbolic (chaotic) quantum systems. Field theoretical methods are applied to compute quantum corrections to the leading (`…
Semiclassical Foundation of Universality in Quantum Chaos
Sebastian Müller, Stefan Heusler, Petr Braun +2
We sketch the semiclassical core of a proof of the so-called Bohigas-Giannoni-Schmit conjecture: A dynamical system with full classical chaos has a quantum energy spectrum with uni…
Quasi-Particle density of states of disordered d-wave superconductors
Bodo Huckestein, Alexander Altland
We present a numerical study of the quasi-particle density of states (DoS) of two-dimensional d-wave superconductors in the presence of smooth disorder. We find power law scaling o…
Field Theory of Mesoscopic Fluctuations in Superconductor/Normal-Metal Systems
Alexander Altland, B. D. Simons, D. Taras-Semchuk
Thermodynamic and transport properties of mesoscopic conductors are strongly influenced by the proximity of a superconductor: An interplay between the large scale quantum coherent…
