'Grey Galaxies' as an endpoint of the Kerr-AdS superradiant instability
Seok Kim, Suman Kundu, Eunwoo Lee +3
Kerr-AdS black holes for suffer from classical superradiant instabilities over a range of masses above extremality. We conjecture that these instabilities settle…
Does the Vacuum Gravitate on Microscopic Scales? Rydberg Atoms Indicate Probably Not
Suman Kumar Kundu, Arnab Pradhan, Carl Rosenzweig
The cosmological constant presents one of the most fascinating and confounding problems in physics. A straightforward, seemingly robust prediction of quantum mechanics and general…
A CFT interpretation of cosmological correlation functions in vacua in de-Sitter space
Sachin Jain, Nilay Kundu, Suman Kundu +2
de-Sitter(dS) space allows for a generalized class of vacua, known as vacua, described by some parameters. The Bunch-Davies (BD) vacua is a point in this parameter space. The c…
Classification of all 3 particle S-matrices quadratic in photons or gravitons
Soumangsu Chakraborty, Subham Dutta Chowdhury, Tushar Gopalka +3
We explicitly construct every kinematically allowed three particle graviton-graviton- and photon-photon- S-matrix in every dimension and for every choice of the little group…
