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 N f = 8 staggered fermions are carried out on 12 × 12 × 24 × 4 lattice. At β =(More)
Responses to chemical potential of the pseudoscalar meson screening mass and the chiral condensate in lattice QCD are investigated. On a 16 × 8 2 ×4 lattice with two flavors of staggered quarks the first and second responses below and above Tc are evaluated. Different behavior in the low and the high temperature phases are observed, which may be explained(More)
