Abstract:

I will discuss the results of thermal lattice QCD simulations showing very unusual behavior of Dirac spectral density at sufficiently high temperatures. Starting from these findings, I will then present arguments leading to the conclusion that, in the corresponding regime, thermal fluctuations act to restore scale invariance at long distances in a non-trivial interacting manner. Implications of this finding for the description of near-perfect fluid medium observed at RHIC and LHC are discussed.
