We study the properties of kigh density hadronic and quark matter in fundamental and phenomenological approaches. First we discuss the phase diagram of quark matter at finite temperature (T) and chemical potential (μ) in the strong coupling limit of lattice QCD for color SU(3) with baryon effects. In an analytically derived expression of the effective free energy as a function of T and μ, baryon effects are shown to extend the hadron phase to a larger chemical potential direction at low temperatures. Next we apply the idea from the strong coupling limit of lattice QCD to the chiral potential in RMF. By introducing logarithmic sigma potential, we can well describe both of the nuclear matter and finite nuclei in a chiral RMF model.
