SUMMARY:Séminaire du LPTMS: Roberto Bondesan - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 25 Fév 14 11:00
DESCRIPTION:Pure scaling operators at the integer quantum Hall plateau tran
 sition\nRoberto Bondesan\, Universität Köln\nStationary wave functions a
 t the transition between plateaus of the integer quantum Hall effect are k
 nown to exhibit multi-fractal statistics. In this talk I will discuss this
  critical behavior for the case of scattering states of the Chalker-Coddin
 gton model with point contacts. I will argue that moments formed from the 
 wave amplitudes of critical scattering states decay as pure powers of the 
 distance between the points of contact and observation. These moments in t
 he continuum limit are proposed to be correlation functions of primary fie
 lds of an underlying conformal field theory. Characterizations of such a t
 heory and extensions of our methods to other systems will be presented. Th
 is is joint work in collaboration with D. Wieczorek (Cologne) and M. Zirnb
 auer (Cologne).
