On the Rényi entropy of Lifshitz and hyperscaling violating black holes

Abstract

We study Rényi entropies for geometries with Lifshitz scaling and hyperscaling violation. We calculate them for specific values of the Lifshitz parameter, and analyze the dual spectrum of the ground state. In the large $d-\theta$ limit they show that the ground state is unique in specific parameter ranges. We also calculate the Rényi entropies perturbatively around $n=1$, and derive constraints using the Rényi entropy inequalities, which correspond to the thermodynamic stability of the black holes.
