SUMMARY:Séminaire du LPTMS: Edouard Boulat - LPTMS\, salle 201\, 2ème ét
 age\, Bât 100\, Campus d'Orsay - 17 Juin 14 11:00
DESCRIPTION:Exact results on the out-of-equilibrium Kondo model\nEdouard Bo
 ulat\, Université Paris Diderot\nTransport in nanoscale quantum devices c
 an be described in many situations by quantum impurity models in which the
  low energy regime is a strong coupling (SC) regime\, an archetypical exam
 ple being the Kondo model. Equilibrium properties in this regime are non p
 erturbative but nevertheless fully accessible using integrability.\nAfter 
 discussing why the exact solution *at equilibrium* cannot be in general ex
 tended to describe the out-of-equilibrium situations\, I will describe a r
 ecently developed framework for integrable quantum impurity models [1]\, i
 n which we can exactly tackle various out-of-equilibrium situations in the
 ir SC regime\, using their equilibrium integrability properties. It allows
  to compute directly the expansion of the universal scaling functions for 
 physical quantities (like the electrical current)\, in principle to arbitr
 arily high order in the driving out-of-equilibrium\, be it voltage\, frequ
 ency... In particular\, we show how to apply this to the Kondo model : our
  approach successfully goes beyond known results for the electrical curren
 t and noise.\n[1] L.Freton and E.Boulat\, PRL 112\, 216802 (2014).
