AbstractWe investigate the behavior of the chiral condensate in lattice QCD at finite temperature and finite chemical potential. The study was done using two flavors of light quarks and with a series of $eta$ and $ma$ at the lattice size $24 imes12^{2} imes6$. The calculation was done in the Taylar expansion formalism. We are able to calculate the first and second order derivatives of $langlear{psi}psi angle$ in both isoscalar and isovector channels. With the first derivatives being small, we find that the second derivatives are sizable close to the phase transition and the magnitude of $ar{psi}psi$ decreases under the influence of finite chemical potential in both channels.
