Chiral transport in strong fields from holography

Anomaly-induced transport phenomena in presence of strong external electromagnetic fields are explored within a 4D field theory defined holographically as \(U(1)_V\times U(1)_A\) Maxwell-Chern-Simons theory in Schwarzschild-\(AdS_5\). Two complementary studies are reported. In the first one, we pres...

Description
Summary:Anomaly-induced transport phenomena in presence of strong external electromagnetic fields are explored within a 4D field theory defined holographically as \(U(1)_V\times U(1)_A\) Maxwell-Chern-Simons theory in Schwarzschild-\(AdS_5\). Two complementary studies are reported. In the first one, we present results on the Ohmic conductivity, diffusion constant, chiral magnetic conductivity, and additional anomaly-induced transport coefficients as functions of external e/m fields. Next, gradient resummation in a constant background magnetic field is performed. All-order resummed constitutive relations are parameterised by four momenta-dependent transport coefficient functions (TCFs). A highlight of this part is a thorough study of {\it non-dissipative} chiral magnetic waves (CMW) in strong magnetic fields.
