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, σ_V, and the chiral magnetic/vortical conductivity of energy current show that σ^ε_B = σ^ε_V. Notably, we highlight a contribution to (σ_V) induced by the mixed term in the massive theory, which is absent in the massless case.
