SUMMARY:Nonequilibrium effects in single-channel and two-channel Kondo
  systems\, R. G. Herb Condensed Matter Seminar\, Aditi Mitra\, New Yor
 k University
DESCRIPTION:It is now experimentally possible to realize both a single
  channel as well as a two channel Kondo system in nanoscale structures
 \, opening up the possibility of studying the nonequilibrium propertie
 s of these systems. After a brief review of the experiments\, I will p
 resent theoretical results for the effect of current flow on a single 
 channel Kondo system\, and the effect of a sudden quench on a two chan
 nel Kondo system. For voltages smaller than the Kondo temperature\, th
 e single channel Kondo system shows behavior consistent with a weakly 
 perturbed Fermi liquid. On the other hand what makes a two channel Kon
 do system interesting is that it is one of the simplest examples of a 
 non-Fermi liquid. It will be shown how this non-Fermi liquid behavior 
 affects the time evolution of the system after a quench.
