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…
