Fidelity susceptibility for Lifshitz geometries via Lifshitz holography

Abstract

In order to analyze the fidelity susceptibility of nonrelativistic field theories, which are important in condensed matter systems, we generalize the proposal to obtain the fidelity susceptibility holographically to Lifshitz geometries. It will be argued that this proposal can be used to study the fidelity susceptibility for various condensed matter systems. To demonstrate this, we will explicitly use this proposal to analyze the fidelity susceptibility for a nonrelativistic many-body system and argue that the fidelity susceptibility of this theory can be holographically obtained from a bulk Lifshitz geometry. In fact, using an Einstein-Dilaton–Maxwell–AdS–Lifshitz theory, we explicitly demonstrated that the fidelity susceptibility obtained from this bulk geometry is equal to the fidelity susceptibility of a bosonic many-body system.
