  We investigate the chemical potential effects of the equation of state and
the chiral transition in an Einstein-Maxwell-dilaton-scalar system, which is
obtained from an improved soft-wall AdS/QCD model coupled with an
Einstein-Maxwell-dilaton system. The equations of state obtained from the model
are in quantitative agreement with the lattice results at both zero and nonzero
chemical potentials. The sensible chiral transition behaviors can be realized
in the model. The QCD phase diagram with a CEP has also been obtained from the
model.
