We consider the implementation of a parallel Monte Carlo code for high-performance simulations on PC clusters with MPI. We carry out tests of speedup and efficiency. The code is used for numerical simulations of pure SU (2) lattice gauge theory at very large lattice volumes, in order to study the infrared behavior of gluon and ghost propaga-tors. This… (More)

Strange quark matter in beta equilibrium at high densities is studied in a quark confinement model. Two equations of state are dynamically generated for the same set of model parameters used to describe the nucleon: one corresponds to a chiral restored phase with almost massless quarks and the other to a chiral broken phase. The chiral symmetric phase… (More)

Equations of state for strange quark matter in beta equilibrium at high densities are used to investigate the structure (mass and radius) of compact objects. The chromodi-electric model is used as a general framework for the quark interactions, which are mediated by chiral mesons, σ and π, and by a confining chiral singlet dynamical field, χ. Using a… (More)
