"Localization transition in QCD at nonzero temperature"
ABSTRACT:
Over 20 years ago Diakanov and Petrov suggested that the chiral phase transition in QCD might be similar to a metal-insulator transition based on the instanton description of the QCD vacuum. The arguments, however, are general and can be applied to other topological objects as well. I will review the proposed connection between QCD and a disordered medium and present some recent results from lattice QCD that are consistent with a localization transition in the lowest eigenmodes of the Dirac operator.
