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…
Spectral correlations in disordered mesoscopic metals and their relevance for persistent currents
Axel Voelker, Peter Kopietz
We use the Lanczos method to calculate the variance of the number of energy levels in an energy window of width E below the Fermi energy for non-interacting disordered electrons on…
How to bosonize fermions with non-linear energy dispersion
Peter Kopietz, Guillermo E. Castilla
We develop a systematic method to treat the effect of non-linearity in the energy dispersion on the usual bosonization result for the single-particle Green's function of fermions i…
Bosonization and the eikonal expansion: similarities and differences
Peter Kopietz
We compare two non-perturbative techniques for calculating the single-particle Green's function of interacting Fermi systems with dominant forward scattering: our recently develope…
Calculation of the average Green's function of electrons in a stochastic medium via higher-dimensional bosonization
Peter Kopietz
The disorder averaged single-particle Green's function of electrons subject to a time-dependent random potential with long-range spatial correlations is calculated by means of boso…
