Frequency-dependence of the Nyquist noise contribution to the dephasing rate in disordered conductors
Axel Voelker, Peter Kopietz
We calculate the Nyquist noise contribution to the dephasing rate 1/τ_{nn}(omega, T) of disordered conductors in d dimensions in the regime where the frequency omega is larger than…
Fermi's golden rule in a mesoscopic metal ring
Peter Kopietz, Axel Voelker
We examine the time-dependent non-equilibrium current in a mesoscopic metal ring threaded by a static magnetic flux phi that is generated by a time-dependent electric field oscilla…
Dephasing in Disordered Conductors due to Fluctuating Electric Fields
Axel Voelker, Peter Kopietz
We develop a novel eikonal expansion for the Cooperon to study the effect of space- and time-dependent electric fields on the dephasing rate of disordered conductors. For randomly…
Non-linear response and electron-electron interactions in mesoscopic metal rings
Peter Kopietz, Axel Voelker
A time-dependent electric field gives rise to a stationary non-equilibrium current I^{(2)} around a mesoscopic metal ring threaded by a magnetic flux. We show that this current, wh…
The weak localization correction to the polarization and persistent currents in mesoscopic metal rings
Peter Kopietz, Axel Voelker
We re-examine the effect of electron-electron interactions on the persistent current in mesoscopic metal rings threaded by an Aharonov-Bohm flux. The exchange contribution to the c…
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…
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…
