  By using the AdS/CFT correspondence, we investigate various form factors
between nucleons and mesons in a nuclear medium. In order to describe a nuclear
medium holographically, we take into account the thermal charged AdS geometry
with an appropriate IR cutoff. After introducing an anomalous dimension as a
free parameter, we investigate how the nucleon's mass is affected by the change
of the anomalous dimension. Moreover, we study how the form factors of nucleons
rely on the properties of the nuclear medium. We show that in a nuclear medium
with different numbers of proton and neutron, the degenerated nucleon form
factor in the vacuum is split to four different values depending on the isospin
charges of nucleon and meson.
