JT gravity and near-extremal thermodynamics for Kerr black holes in for rotating perturbations
Rohan R. Poojary
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 and exce…
Fast Scrambling of mutual information in Kerr-AdS
Vinay Malvimat, Rohan R. Poojary
We compute the disruption of mutual information in a TFD state dual to a Kerr black hole with equal angular momenta in due to an equatorial shockwave. The shockwave respect…
Jackiw-Teitelboim gravity and near-extremal BTZ thermodynamics
Rohan R. Poojary
We study the near horizon 2d gravity theory which captures the near extremal thermodynamics of BTZ with excess mass and excess angular momentum over ext…
Fast Scrambling of Mutual Information in Kerr-AdS
Vinay Malvimat, Rohan R. Poojary
We compute the disruption of mutual information between the hemispherical subsystems on the left and right CFT of a Thermofield Double state described by a Kerr geometry in $AdS…
Fast Scrambling due to Rotating Shockwaves in BTZ
Vinay Malvimat, Rohan R. Poojary
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 C…
Reparametrization mode Ward Identities and chaos in higher-pt. correlators in CFT
Arnab Kundu, Ayan K. Patra, Rohan R. Poojary
Recently introduced reparametrization mode operators in CFTs have been shown to govern stress tensor interactions the shadow operator formalism and seem to govern the effecti…
Rotating Black Holes in AdS, Extremality and Chaos
Avik Banerjee, Arnab Kundu, Rohan R. Poojary
Extremal black holes have vanishing Hawking temperatures. In this article, we argue that for asymptotically AdS black holes, at extremality, a particular class of correlators in th…
BTZ dynamics and chaos
Rohan R. Poojary
We find an effective action for gravitational interactions with scalars in to first order in at the conformal boundary. This action can be understood as an action for…
Maximal Chaos from Strings, Branes and Schwarzian Action
Avik Banerjee, Arnab Kundu, Rohan Poojary
In this article, we explicitly demonstrate that, for a sufficiently generic class of examples, an open string embedded in an AdS-background yields an effective Schwarzian action an…
Strings, Branes, Schwarzian Action and Maximal Chaos
Avik Banerjee, Arnab Kundu, Rohan R. Poojary
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 gauge theory. I…
On Asymptotic Symmetries of 3d Extended Supergravities
Rohan R. Poojary, Nemani V. Suryanarayana
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-Dirich…
Notes on Melonic Tensor Models
Sayantan Choudhury, Anshuman Dey, Indranil Halder +3
It has recently been demonstrated that the large N limit of a model of fermions charged under the global/gauge symmetry group agrees with the large limit of the SY…
A Note on S-Matrix Bootstrap for Amplitudes with Linear Spectrum
Pranjal Nayak, Rohan R. Poojary, Ronak M Soni
We work out constraints imposed by channel duality and analyticity on tree-level amplitudes of four identical real scalars, with the assumptions of a linear spectrum of exchanged p…
Holographic chiral induced W-gravities
Rohan R. Poojary, Nemani V. Suryanarayana
We study boundary conditions for 3-dimensional higher spin gravity that admit asymptotic symmetry algebras expected of 2-dimensional induced higher spin theories in the light cone…
An sl(2, R) current algebra from AdS_3 gravity
Steven G. Avery, Rohan R. Poojary, Nemani V. Suryanarayana
We provide a set of chiral boundary conditions for three-dimensional gravity that allow for asymptotic symmetries identical to those of two-dimensional induced gravity in light-con…
