Simulation of SU(2) Dynamical Fermion at Finite Chemical Potential and at Finite Temperature
Abstract
SU(2) lattice gauge theory with dynamical fermion at non-zero chemical potential and at finite temperature is studied. We focus on the influence of chemical potential for quark condensate and mass of pseudoscalar meson at finite temperature. Hybrid Monte Carlo simulations with Nf=8 staggered fermions are carried out on 12 × 12× 24 × 4 lattice. At β=1.1 and mq=0.05,0.07,0.1, we calculate the quark condensate and masses of pseudoscalar meson consisting of light and heavier quarks for chemical potential μ= 0.0,0.02,0.05,0.1,0.2.
