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…
Negative shocks versus static patch holography
Yiming Chen, Douglas Stanford, Haifeng Tang +1
We study a version of de Sitter static patch holography in which the Euclidean gravitational path integral, with an observer worldline included, is conjectured to compute a trace.…
One-loop aspects of de Sitter axion wormholes
Victor Ivo, Haifeng Tang
We discuss aspects of the Euclidean path integral around axion-supported de Sitter wormholes, at one-loop order. We numerically compute the phase of the path integral around these…
A Two-Point Hologram for Everything
Tamra Nebabu, Xiao-Liang Qi, Haifeng Tang +1
Known holographic dictionaries, especially AdS/CFT, rely on symmetry matching between the bulk and the boundary. We take a step toward a holographic dictionary with no symmetry req…
