The critical line from imaginary to real baryonic chemical potentials in two-color QCD

Paolo Cea, Leonardo Cosmai, Massimo D'Elia +1

The method of analytic continuation from imaginary to real chemical potentials is one of the few available techniques to study QCD at finite temperature and baryon density. One…

Numerical study of the mass spectrum in the 2D O(3) sigma model with a theta term

B. Alles, A. Papa

It has been conjectured that the mass spectrum of the O(3) non-linear sigma model with a theta term in 2 dimensions may possess an excited state, which decays when theta is lowered…

Analytic continuation of the critical line in 2-color QCD at nonzero temperature and density

Paolo Cea, Leonardo Cosmai, Massimo D'Elia +1

We determine the pseudo-critical line in the temperature - chemical potential plane of 2-color QCD by direct Monte Carlo simulations and by analytic continuation from imaginary che…

Screening masses in the SU(3) pure gauge theory and universality

Rossella Falcone, Roberto Fiore, Mario Gravina +1

We determine from Polyakov loop correlators the screening masses in the deconfined phase of the (3+1)d SU(3) pure gauge theory at finite temperature near the transition, for two di…

The spectrum of massive excitations of 3d 3-state Potts model and universality

Rossella Falcone, Roberto Fiore, Mario Gravina +1

We consider the mass spectrum of the 3 3-state Potts model in the broken phase (a) near the second order Ising critical point in the temperature - magnetic field plane and (b) n…

QED_3 on a space-time lattice: a comparison between compact and noncompact formulation

Roberto Fiore, Pietro Giudice, Domenico Giuliano +3

Quantum electrodynamics in a (2+1)-dimensional space-time has been object of studies both as effective theory for the pseudogap phase of high-T_c superconductors and for the theore…
