Holographic mutual and tripartite information in a non-conformal background

Holographic mutual and tripartite information have been studied in a non-conformal background. We have investigated the effect of the energy scale and the difference in degrees of freedom between the UV and IR fixed points of the theory on these observables. We have found out that the effect of these parameters is opposite. Moreover, the two sub-regions in NCFT become disentangled in larger separation distance than CFT independent of the length of them. The mutual information in a non-conformal background remains also monogamous. (C) 2021 The Authors. Published by Elsevier B.V.
