Abstract We compute the disruption of mutual information in a TFD state dual to a Kerr black hole with equal angular momenta in AdS 5 due to an equatorial shockwave. The shockwave respects the axi-symmetry of the Kerr geometry with specific angular m

Abstract We study the near horizon 2d gravity theory which captures the near extremal thermodynamics of Kerr black holes where a linear combination of excess angular momentum δJ and excess mass δM is held fixed. These correspond to processes where

In this article, we present explicit evidence that maximal chaos occurs for a generic, probe quark-like defect degrees of freedom, in a strongly coupled large Nc gauge theory. In holography, this corresponds to the dynamics of open string degrees of

Abstract We find an effective action for gravitational interactions with scalars in AdS 3 to first order in G N at the conformal boundary. This action can be understood as an action for the Brown-Henneaux modes and is given by the square-root product

Abstract We study asymptotic symmetry algebras for classes of three dimensional supergravities with and without cosmological constant. In the first part we generalise some of the non-dirichlet boundary conditions of AdS 3 gravity to extended supergra

Abstract It has recently been demonstrated that the large N limit of a model of fermions charged under the global/gauge symmetry group O(N) q−1 agrees with the large N limit of the SYK model. In these notes we investigate aspects of the dynamics of

We compute the disruption of mutual information between the hemispherical subsystems on the left and right conformal field theories of a thermofield double state described by a Kerr geometry in AdS4 due to shock waves along the equatorial plane. The

We study the perturbation due to rotating shockwaves in BTZ geometries at late times and analyse the change in Mutual Information between the two subsystems belonging to the dual CFT$_L$ and CFT$_R$. We find that the scrambling of Mutual Information
