Holographic DC conductivity for backreacted nonlinear electrodynamics with momentum dissipation
Abstract We consider a holographic model with the charge current dual to a general nonlinear electrodynamics (NLED) field. Taking into account the backreaction of the NLED field on the geometry and introducing axionic scalars to generate momentum dissipation, we obtain expressions for DC conductivit...
