Monte Carlo Study of Lattice QCD with Wilson fermions at Finite Temperature and Chemical Potential

摘要

In this paper, we studied the phase diagram of QCD at finite temperature T and chemical potential μ with 4 flavor Wilson quarks. The calculations are performed on a 8~3 × 4 lattice using the imaginary chemical potential method. This method allows us to do large scale Monte Carlo simulations at imaginary chemical potential μ = iμ_1 with μ_1 < πT/3. By analytic continuation to the real chemical potential, the phase transition line on the (μ,T) plane can be determined.
