Simulation of Wilson fermion at finite isospin density

Abstract

For QCD with Wilson fermions at isospin chemical potential we study the finite phase transition on an $8^3\times 4$ lattice at $\kappa =0.15$. We use two gauge actions: Wilson action and DBW2 action. Both actions give the same results. The phase diagram is qualitatively similar to the one obtained for QCD at small baryon chemical potential. We also calculate the number density for various isospin chemical potentials.
