Theta dependence of 4D SU(N) gauge theories at finite temperature
Claudio Bonati, Massimo D'Elia, Haralambos Panagopoulos +1
We report a study of the dependence of 4D SU(N) gauge theories on the topological theta term at finite temperature, and in particular in the large-N limit. We show that the theta d…
Relevance of the axial anomaly at the finite-temperature chiral transition in QCD
Andrea Pelissetto, Ettore Vicari
We investigate the nature of the finite-temperature chiral transition in QCD with two light flavors, in the case of an effective suppression of the the U(1)_A symmetry breaking ind…
Universal behavior of two-dimensional bosonic gases at Berezinskii-Kosterlitz-Thouless transitions
G. Ceccarelli, J. Nespolo, A. Pelissetto +1
We study the universal critical behavior of two-dimensional (2D) lattice bosonic gases at the Berezinskii-Kosterlitz-Thouless (BKT) transition, which separates the low-temperature…
Equilibrium and nonequilibrium entanglement properties of 2D and 3D Fermi gases
Jacopo Nespolo, Ettore Vicari
We investigate the entanglement properties of the equilibrium and nonequilibrium quantum dynamics of 2D and 3D Fermi gases, by computing entanglement entropies of extended space re…
Change of theta dependence in 4D SU(N) gauge theories across the deconfinement transition
Claudio Bonati, Massimo D'Elia, Haralambos Panagopoulos +1
We investigate the dependence of four-dimensional SU(N) gauge theories on the topological theta term at finite temperature and, in particular, across the deconfinement transition.…
