A non-prompt null ray cures its own singularity
Gauri Batra
In AdS/CFT correlators, bulk cone singularities arise when two points that are timelike separated on the AdS boundary may be connected by a null geodesic through the bulk. We consi…
A backreacted bouncing geodesic in 2D
Gauri Batra, Adam Levine, Stephen H. Shenker
In holography, analytically continued finite temperature correlation functions exhibit signatures of the black hole singularity. These take the form of singularities at cert…
An effective field theory approach to the sign problem in BFSS
Gauri Batra, Henry W. Lin, Haifeng Tang
The sign problem is a notorious obstacle for classically simulating quantum theories with fermions. We propose an effective field theory method for analyzing the sign problem. At h…
The yes boundaries wavefunctions of the universe
Batoul Banihashemi, Gauri Batra, Y. T. Albert Law +2
A generic spacetime topology contains timelike boundaries. Making use of two such boundaries, we formulate a microscopic holographic dual that captures cosmological spacetime beyon…
Giant gravitons in D-brane holography
Gauri Batra, Henry W. Lin
We consider half BPS operators in maximally supersymmetric Yang Mills (SYM) in dimensions. These operators satisfy trace relations that are identical to those discussed in th…
Timelike boundaries in de Sitter JT gravity and the Gao-Wald theorem
Gauri Batra
The Gao-Wald theorem says that de Sitter spacetime reacts to a positive energy perturbation by getting "taller." How does this change in the presence of timelike boundaries? We stu…
Bulk-local dS holography: the Matter with
Gauri Batra, G. Bruno De Luca, Eva Silverstein +2
We propose an algorithm which builds a concrete dual for large-radius 3d de Sitter with a timelike York boundary for both gravity and bulk effective fields. This generalizes the so…
Non-Axisymmetric Precession of Magnetars and Fast Radio Bursts
Ira Wasserman, James M. Cordes, Shami Chatterjee +1
The repeating FRBs 180916.J0158 and 121102 are visible during periodically-occuring windows in time. We consider the constraints on internal magnetic fields and geometry if the cyc…
