Title:
The Dirac eigenvalues in high temperature QCD: connection with topology and RMT.

Speaker:
Sayantan Sharma

Abstract:
The QCD Dirac eigenvalue spectrum has rich information about the strong interaction dynamics. I would present our recent work on the eigenvalue spectrum of QCD with chiral fermions on the lattice. We observe that the near-zero eigenvalues at T>1.2 T_c, the chiral crossover temperature, can be explained from a weakly interacting instanton gas. The bulk eigenvalues also have many interesting properties. Not only do these contribute to U_A(1) breaking but also have level spacing fluctuations and other properties that can be described using Random Matrix Theory.
