SUMMARY:Séminaire du LPTMS: Max Atkin - LPTMS\, salle 201\, 2ème étage\,
  Bât 100\, Campus d'Orsay - 25 Juin 13 11:00
DESCRIPTION:From Instantons to Large Deviations in Hermitian Random Matrice
 s\nMax Atkin (University of Bielefeld)\nThe typical fluctuations of the la
 rgest eigenvalue of a Hermitian random matrix about its mean has been know
 n for a long time to be given by the Tracy-Widom distribution. More recent
 ly interest has focused on the 'atypical' fluctuations in which an eigenva
 lue appears very far from the bulk spectrum. This problem has been attacke
 d using saddle point methods\, loop equations and\, to a much lesser exten
 t\, orthogonal polynomials. In this talk we review recent progress in the 
 orthogonal polynomial approach which makes contact with instanton effects 
 in the string theory literature. We use this framework to derive the distr
 ibution for large deviations in the case of multi-critical potentials.
