"Localization transition in QCD at nonzero temperature"
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.
