Screening of persistent currents in mesoscopic metal rings
Axel Voelker, Peter Kopietz
The effect of the Coulomb-interaction on persistent currents in disordered mesoscopic metal rings threaded by a magnetic flux is studied numerically. We use the simplest form o…
Quasi-particle behavior of composite fermions in the half-filled Landau level
Peter Kopietz, Guillermo E. Castilla
We calculate the effect of infrared fluctuations of the Chern-Simons gauge field on the single-particle Green's function of composite fermions in the half-filled Landau level via h…
Knot Theory of Coxeter type B and its physical applications
Reinhard Häring-Oldenburg
Braid groups may be defined for every Coxeter diagram. Artin's braid group is of type A. Analogs of Temperley-Lieb, Hecke and Birman-Wenzl algebras exist for B-type. Our general hy…
Quantum Zeno Effect and Light-Dark Periods for a Single Atom
Almut Beige, Gerhard C. Hegerfeldt
The quantum Zeno effect (QZE) predicts a slow-down of the time development of a system under rapidly repeated ideal measurements, and experimentally this was tested for an ensemble…
What determines the spreading of a wave packet?
R. Ketzmerick, K. Kruse, S. Kraut +1
The multifractal dimensions D2^mu and D2^psi of the energy spectrum and eigenfunctions, resp., are shown to determine the asymptotic scaling of the width of a spreading wave packet…
Replica Symmetry Breaking and the Kuhn-Tucker Cavity Method in simple and multilayer Perceptrons
F. Gerl, U. Krey
Within a Kuhn-Tucker cavity method introduced in a former paper, we study optimal stability learning for situations, where in the replica formalism the replica symmetry may be brok…
