Poisson to Random Matrix Transition in the QCD Dirac Spectrum
Tamas G. Kovacs, Ferenc Pittler
At zero temperature the lowest part of the spectrum of the QCD Dirac operator is known to consist of delocalized modes that are described by random matrix statistics. In the presen…
High temperature quark localization by Polyakov loops
Tamas G. Kovacs, Ferenc Pittler, Falk Bruckmann +1
We study the low eigenmodes of the overlap and staggered Dirac operator at high temperature. We show that the recently found localized quark modes obeying Poisson statistics are co…
Anderson localization through Polyakov loops: lattice evidence and Random matrix model
Falk Bruckmann, Tamás G. Kovács, Sebastian Schierenberg
We investigate low-lying fermion modes in SU(2) gauge theory at temperatures above the phase transition. Both staggered and overlap spectra reveal transitions from chaotic (random…
Anderson Localization in Quark-Gluon Plasma
Tamas G. Kovacs, Ferenc Pittler
At low temperature the low end of the QCD Dirac spectrum is well described by chiral random matrix theory. In contrast, at high temperature there is no similar statistical descript…
Absence of correlations in the QCD Dirac spectrum at high temperature
Tamas G. Kovacs
I propose a simple model of the distribution of the small eigenvalues of the QCD Dirac operator well above the finite temperature phase transition where chiral symmetry is restored…
Gapless Dirac Spectrum at High Temperature
Tamas G. Kovacs
Using the overlap Dirac operator I show that, contrary to some expectations, even well above the critical temperature there is not necessarily a gap in the Dirac spectrum in pure S…
