Phase structure of four flavor QCD in the T μplane from a new method for simulations of lattice gauge theories at non zero baryon density
Vicente Azcoiti, Giuseppe Di Carlo, Angelo Galante +1
We review a method for numerical simulations of lattice gauge theories at non-zero baryonic chemical potential we recently proposed. We first report on a test of the method using a…
Vector Symmetries and Theta-Vacuum
V. Azcoiti, A. Galante
Under very general assumptions we show that Vafa-Witten theorem on vector symmetries in vector-like theories can be extended to some physically relevant gauge theories with non-pos…
The role of the Polyakov loop in the Dirac operator of QCD at finite temperature
Vicente Azcoiti
We show how all the contributions to the determinant of the Dirac-Kogut-Susskind operator of QCD at finite temperature containing a net number of Polyakov loops become irrelevant i…
Complex Probability Distributions: A Solution for the Long-Standing Problem of QCD at Finite Density
Vicente Azcoiti
We show how the prescription of taking the absolute value of the fermion determinant in the integration measure of QCD at finite density, forgetting its phase, reproduces the corre…
Renormalization Group And Scaling Within The Microcanonical Fermionic Average Approach
V. Azcoiti, V. Laliena, G. Di Carlo +2
The MFA approach for simulations with dynamical fermions in lattice gauge theories allows in principle to explore the parameters space of the theory (e.g. the plane for the…
