Lattice simulation of $Q{C}_{2}D$ with $N_f=2$ at non-zero baryon density

Abstract

The lattice simulations of $Q{C}_{2}D$ with two flavors of staggered fermions and non-zero quark chemical potential ${\mu }_q$ have been performed. Dependencies of the Polyakov loop, chiral condensate and baryon number density on ${\mu }_q$ were studied. We found that an increase of the baryon chemical potential leads to chiral symmetry restoration. At small values of ${\mu }_q$, our results for the baryon number density agree with ChPT predictions.
