Susceptibilities from Holographic Transport with Topological Term

Abstract

In this note, we calculate susceptibilities, as derivatives of a thermodynamical potential, for the general perturbative holographic setup for transport with magnetic field, charge density and topological term, and compare with the quantities obtained in the standard AdS4$$AdS_4$$ dyonic black hole analysis of Hartnoll and Kovtun. We find that the results do not match, despite previous expectations.
