Query: Holographic Chiral Electric Separation Effect   We investigate the chiral electric separation effect, where an axial current
is induced by an electric field in the presence of both vector and axial
chemical potentials, in a strongly coupled plasma via the Sakai-Sugimoto model
with an $U(1)_R\times U(1)_L$ symmetry. By introducing different chemical
potentials in $U(1)_R$ and $U(1)_L$ sectors, we compute the axial direct
current (DC) conductivity stemming from the chiral current and the normal DC
conductivity. We find that the axial conductivity is approximately proportional
to the product of the axial and vector chemical potentials for arbitrary
magnitudes of the chemical potentials. We also evaluate the axial alternating
current (AC) conductivity induced by a frequency-dependent electric field,
where the oscillatory behavior with respect to the frequency is observed.
