Holographic approach to anomalous transport in a massive $U(1)$ gauge theory

Abstract

In this study, we explore a massive (U(1)) gauge holographic model with pure gauge and mixed gauge-gravitational Chern-Simons terms. By considering the full backreaction of the gauge field on the metric tensor, we explore the vortical and energy transport sectors. Our findings for the chiral vortical conductivity, ${\sigma }_V$, and the chiral magnetic/vortical conductivity of energy current show that ${\sigma }_B^{\epsilon }={\sigma }_V^{\epsilon }$. Notably, we highlight a contribution to (σ_V) induced by the mixed term in the massive theory, which is absent in the massless case.
