Query: On the Chiral Magnetic Effect in Soft-Wall AdS/QCD   The essence of the chiral magnetic effect is generation of an electric
current along an external magnetic field. Recently it has been studied by
Rebhan et al. within the Sakai--Sugimoto model, where it was shown to be zero.
As an alternative, we calculate the chiral magnetic effect in soft-wall AdS/QCD
and find a non-zero result with the natural boundary conditions. The mechanism
of the dynamical neutralization of the chiral chemical potential via the string
production is discussed in the dual two-form representation.
