  We study the transport coefficients, including the conductivities and shear
viscosity of the non-relativistic field theory dual to the Lifshitz black brane
with multiple U(1) gauge fields by virtue of the gauge/gravity duality.
Focusing on the case of double U(1) gauge fields, we systematically investigate
the electric, thermal and thermoelectric conductivities for the dual
non-relativistic field theory. In the large frequency regime, we find a
nontrivial power law behavior in the electric AC conductivity when the
dynamical critical exponent z>1 in (2+1)-dimensional field theory. The
relations between this novel feature and the `symmetric hopping model' in
condensed matter physics are discussed. In addition, we also show that the
Kovtun-Starinets-Son bound for the shear viscosity to the entropy density is
not violated by the additional U(1) gauge fields and dilaton in the Lifshitz
black brane.
