## Abstract

N = 2 supersymmetric Yang-Mills theory with flavor hypermultiplets at finite temperature is studied for finite quark number density (n_{b}) by a dual supergravity background with nontrivial dilaton and axion. The quarks and their number density n_{b} are introduced by embeddings a probe D7 brane. We find a critical value of the chemical potential at the limit of n _{b} = 0, and it coincides with the effective quark mass for n _{b} = 0. At this point, a transition of the D7 embedding configurations occurs between their two typical ones. The phase diagrams of this transition are shown in the plane of chemical potential versus temperature for Yang-Mills theory at finite temperature. In this phase transition, the order parameter is considered as n_{b}. This result seems to be reasonable since this theory is in the quark deconfiment phase.
