Improved transport equations including correlations for electron-phonon systems. Comparison with exact solutions in one dimension
J. Fricke, V. Meden, C. Wohler +1
We study transport equations for quantum many-particle systems in terms of correlations by applying the general formalism developed in an earlier paper to exactly soluble electron-…

Dynamic response of mesoscopic metal rings and thermodynamics at constant particle number
Jens Fricke, Peter Kopietz
We show by means of simple exact manipulations that the thermodynamic persistent current in a mesoscopic metal ring threaded by a magnetic flux at constant particl…
