As the long wavelength limit of the AdS/CFT correspondence, the gravity/fluid
correspondence has been shown to be a useful tool for extracting properties of
the fluid on the boundary dual to the gravity in the bulk. In this paper, after
briefly reviewing the algorithm of gravity/fluid correspondence, we discuss the
results of its application on bulk gravity with a U(1) gauge field. In the
presence of a U(1) gauge field, the dual fluid possesses more interesting
properties such as its charge current. Furthermore, an external field
Aμext could affect the charge current, and the U(1) Chern-Simons term
also reinduces extra structures to the dual current giving anomalous transport
coefficients.Comment: 14 pages, no figure, version publishe
