Dirichlet gravitons in AdS and wedge algebra
Hare Krishna
We derive the AdS deformation of the flat-space soft-graviton algebra with Dirichlet boundary conditions. Starting from the AdS spinor-helicity representation, we Mellin-transf…
Aspects of Carrollian field theory from holography
Hare Krishna, Vaishnavi Patil
We study holography for three-dimensional asymptotically flat spacetimes in which the bulk gravitational dynamics is conjectured to be dual to a two-dimensional Carrollian (equival…
Holographic entanglement entropy with conformal boundary conditions
Elena Cáceres, Hare Krishna, Harita Palani Balaji +1
We study holographic entanglement entropy in 3-dimensional AdS gravity with conformal boundary conditions which fix the conformal class of the boundary metric and its extrinsic cur…
Seeing double: shock waves and the de Sitter horizon
Willy Fischler, Hare Krishna, Sarah Racz
We consider a de Sitter observer in his rest frame at late times who observes a particle slightly displaced from unstable equilibrium. Initially, the observer notices an axisymmetr…
There is more to the de Sitter horizon than just the area
Willy Fischler, Hare Krishna, Sarah Racz
It is well known that the area of the de Sitter cosmological horizon is related to the entropy of the bulk spacetime. Recent work has however shown that the horizon encodes more in…
Topologically charged BPS microstates in AdS/CFT
Arash Arabi Ardehali, Hare Krishna
In the standard AdS/CFT with , as well as the Datta-Eberhardt-Gaberdiel variant with $\mathrm{sym}^N(T^4/\mathb…
Celestial gluon and graviton OPE at loop level
Hare Krishna
In this paper, we analyze the loop corrections to celestial OPE for gluons and gravitons. Even at the loop level, the soft gluons and gravitons have conformal dimensions $Δ=1-\math…
Universality of Loop Corrected Soft Theorems in 4d
Hare Krishna, Biswajit Sahoo
In \cite{1808.03288}, logarithmic correction to subleading soft photon and soft graviton theorems have been derived in four spacetime dimensions from the ratio of IR-finite S-matri…
Celestial holography from Chiral strings
Hare Krishna, Yu-Ping Wang
In this paper, we studied the relationship between celestial holography and chiral strings. Chiral strings differ from the usual string theory by a change of boundary conditions on…
Modified supersymmetric indices in AdS/CFT
Arash Arabi Ardehali, Hare Krishna
We consider the AdS/CFT dualities proposed by Eberhardt, where the bulk geometry is AdS, and the CFT is a deformat…
Holographic thermal correlators revisited
Hare Krishna, D. Rodriguez-Gomez
We study 2-point correlation functions for scalar operators in position space through holography including bulk cubic couplings as well as higher curvature couplings to the square…
Light-Cone Reduction vs. TsT transformations : A Fluid Dynamics Perspective
Suvankar Dutta, Hare Krishna
We compute constitutive relations for a charged dimensional Schrödinger fluid up to first order in derivative expansion, using holographic techniques. Starting with a local…
