We study the physics with finite nuclear density in the framework of AdS/QCD
with holographic baryon field included. Based on a mean field type approach, we
introduce the nucleon density as a bi-fermion condensate of the lowest mode of
the baryon field and calculate the density dependence of the chiral condensate
and the nucleon mass. We observe that the chiral condensate as well as the mass
of nucleon decrease with increasing nuclear density. We also consider the mass
splitting of charged vector mesons in iso-spin asymmetric nuclear matter.Comment: 16 pages, 3 figures, two references are added, typo corrected,
