Özet
İngilizce (OpenAlex)
We discuss a possible dependence of the chiral magnetic effect (CME) on the elliptic flow coefficient ${v}_{2}$. We first study this in a hydrodynamic model for a static anisotropic plasma with multiple anomalous $U(1)$ currents. In the case of two charges, one axial and one vector, the CME formally appears as a first-order transport coefficient in the vector current. We compute this transport coefficient and show its dependence on ${v}_{2}$. We also determine the CME coefficient from first-order corrections to the dual anti-de Sitter background using the fluid-gravity duality. For small anisotropies, we find numerical agreement with the hydrodynamic result.
