Query: Chiral magnetic effect and holography   The chiral magnetic effect (CME) is a highly discussed effect in heavy-ion
collisions stating that, in the presence of a magnetic field B, an electric
current is generated in the background of topologically nontrivial gluon
fields. We present a holographic (AdS/CFT) description of the CME in terms of a
fluid-gravity model which is dual to a strongly-coupled plasma with multiple
anomalous U(1) currents. In the case of two U(1) charges, one axial and one
vector, the CME formally appears as a first-order transport coefficient in the
vector current. We will holographically compute this coefficient at strong
coupling and compare it with the hydrodynamic result. Finally, we will discuss
an anisotropic variant of the model and study a possible dependence of the CME
on the elliptic flow coefficient v_2.
