Chiral Polarization Scale at Finite Temperature

الأصل · EN

We study the chiral polarization properties of low-lying Dirac eigenmodes at finite temperature using the overlap operator. Results for pure gauge theory on both sides of deconfinement phase transition are presented. We find that the polarization scale decreases as we increase the temperature, but it remains non-zero as we cross in the deconfined phase and vanishes only when T≈ 1.4 Tc. This is caused by the presence of near-zero modes which, we find, are chirally polarized.
