Microscopic origin of U sub(A)(1) symmetry violation in the high temperature phase of QCD

We investigate the low-lying eigenmodes of the Dirac matrix with the aim to gain more insight into the temperature dependence of the anomalous U sub(A)(1) symmetry in QCD. We use the overlap operator to probe dynamical QCD configurations generated with (2 + 1)-flavors of highly improved staggered qu...
