Anderson localization in sigma models


  • Mr. jacob WELLNHOFER

Primary authors


In QCD above the deconfinement temperature there exists an Anderson transition in the fermion spectrum from localized to delocalized modes. We investigate whether the same holds for nonlinear sigma models. In particular we study the spectra of fermions coupled to (quenched) CP(N-1) configurations at high temperatures. We compare results in two and three space-time dimensions: in two dimensions the Anderson transition is absent, while in three dimensions it is present.
