  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 $12 \times 12\times 24 \times 4$ lattice. At $\beta=1.1$ and
$m_{q}=$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 $\mu=$ 0.0,0.02,0.05,0.1,0.2.
