Revisiting strong coupling QCD at finite temperature and baryon density

The strong coupling limit (βgauge = 0) of lattice QCD with staggered fermions enjoys the same non-perturbative properties as continuum QCD, namely confinement and chiral symmetry breaking. In contrast to the situation at weak coupling, the sign problem which appears at finite density can be brought under control for a determination of the full (μ ,T ) phase diagram by Monte Carlo simulations. F...

Condensates in Two Colours Finite Density QCD at Strong Coupling

We study unquenched lattice SU(2) at nonzero chemical potential at strong coupling and with eight flavours of Kogut-Susskind fermions. Introducing a diquark source term we analyze the behaviour of different types of fermion condensates. Using a non standard approach we can obtain results at zero external source without extrapolations. We find strong evidences for a (high density) second order p...

Strongly Coupled QCD at Finite Baryon Density

Finite Density QCD is affected by the well known sign problem that has prevented, in most cases, any success in simulate this theory and, until now, no solution is at sight. The only exceptions in this scenario are strong coupling simulations performed with the Monomer Dimer Polymer (MDP) algorithm [1]. This algorithm is able to provide results not affected by early onset and in partial agreeme...

On the QCD Phase Transition at Finite Baryon Density

We investigate the QCD chiral phase transition at finite chemical potential μ, using the renormalization group (RG) to characterize the infrared behavior of sigma models constrained by the flavor and spacetime symmetries. The results are similar to those obtained from RG analysis of the finite temperature transition at zero baryon density. When there are more than two massless flavors of quarks...

QCD at Finite Baryon Density: Nucleon Droplets and Color Superconductivity

We use a variational procedure to study finite density QCD in an approximation in which the interaction between quarks is modelled by that induced by instantons. We find that uniform states with conventional chiral symmetry breaking have negative pressure with respect to empty space at all but the lowest densities, and are therefore unstable. This is a precisely defined phenomenon which motivat...
