Polyakov loops from Dirac spectra — Erek Bilgici2, •Falk Bruckmann1, Christof Gattringer2, and Christian Hagen1 — 1Institut für Theoretische Physik, Universität Regensburg — 2Institut für Physik, FB Theoretische Physik, Universität Graz
For QCD at finite temperature, the Polyakov loop and the chiral condensate are two order parameters characterizing the deconfinement and chiral phase transition, respectively. We present a method that aims at relating the two by representing lattice Polyakov loops through spectral sums of lattice Dirac (or Laplace) operators. By virtue of numerical results we analyze the role of the eigenvalues in the spectral sums and the possibility to define dressed Polyakov loops in this way.
