Mesoscopic fluctuations in the Fermi-liquid regime of the Kondo problem
Abstract
We consider the low temperature regime of the mesoscopic Kondo problem, and in particular
the relevance of a Fermi-liquid description of this regime. Mesoscopic fluctuations
of both the quasiparticle energy levels and the corresponding wavefunctions are large
in this case. These mesoscopic fluctuations make the traditional approach to Fermi-liquids
impracticable, as it assumes the existence of a limited number of relevant parameters.
We show here how this difficulty can be overcome and discuss the relationship between
the resulting Fermi-liquid description "à la Nozières" and the mean field slave fermion
approximation. © 2013 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

The broad focus of Prof. Baranger's group is quantum open systems at the nanoscale,
particularly the generation of correlation between particles in such systems. Fundamental
interest in nanophysics-- the physics of small, nanometer scale, bits of solid-- stems
from the ability to control and probe systems on length scales larger than atoms but
small enough that the averaging inherent in bulk properties has not yet occurred.
Using this ability, entirely unanticipated phenomena ca
