The Fate of Information Localizability and Holography in Quantum Gravity
Hao Geng, Daniel Jafferis, Pushkal Shrivastava +1
The AdS/CFT correspondence states an equivalence between a quantum gravitational theory in a (d+1)-dimensional anti-de Sitter spacetime (AdS) and a d-dimensional conformal…
The S-matrix and boundary correlators in flat space
Diksha Jain, Suman Kundu, Shiraz Minwalla +3
We consider the path integral of a quantum field theory in Minkowski spacetime with fixed boundary values (for the elementary fields) on asymptotic boundaries. We define and study…
Squinting at massive fields from infinity
Alok Laddha, Siddharth G. Prabhu, Suvrat Raju +1
We study a novel asymptotic limit of massive scalar fields in nongravitational quantum field theories in four-dimensional flat space. We foliate the spacetime into a set of dS…
Quantum aspects of charged black holes in de-Sitter space
Pushkal Shrivastava
It has been argued that generic classical perturbations to asymptotically de-Sitter Reissner-Nordtsröm (RN-dS) black holes may violate strong cosmic censorship conjecture. In this…
The Holographic Nature of Null Infinity
Alok Laddha, Siddharth G. Prabhu, Suvrat Raju +1
We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat spacetime, all information about massless excitations can be obtained from an infinitesimal…
A simple quantum test for smooth horizons
Kyriakos Papadodimas, Suvrat Raju, Pushkal Shrivastava
We develop a new test that provides a necessary condition for a quantum state to be smooth in the vicinity of a null surface: near-horizon modes that can be defined locally near an…
A Bound on Thermal Relativistic Correlators at Large Spacelike Momenta
Souvik Banerjee, Kyriakos Papadodimas, Suvrat Raju +2
We consider thermal Wightman correlators in a relativistic quantum field theory in the limit where the spatial momenta of the insertions become large while their frequencies stay f…
A Critique of the Fuzzball Program
Suvrat Raju, Pushkal Shrivastava
We explore the viability of fuzzballs as candidate microstate geometries for the black hole, and their possible role in resolutions of the information paradox. We argue that if fuz…
