Query: A hQCD model and its phase diagram in Einstein-Maxwell-Dilaton system   By use of the potential reconstruction approach we obtain a series of
asymptotically AdS (aAdS) black hole solutions in an Einstein-Maxwell-Dilaton
(EMD) system. Basing on the solutions of the system, we reconstruct a
semi-analytical holographic QCD (hQCD) model with a quadratic term in warped
factor. We discuss some aspects of the hQCD model, in particular we calculate
the free energy of two static color sources (a heavy quark-antiquark pair)
which is an important order parameter to describe confinement/deconfinement
phase transition. The behavior of the free energy with respect to temperature
and chemical potential is studied. We find that in the hQCD model the
deconfinement phase transition can be realized and a critical point occurs. The
resulting phase diagram in the temperature-chemical potential $T-\mu$ plane is
in quite good agreement with the one from recent lattice results and effective
models of QCD.
