Holographic duality from Howe duality: Chern-Simons gravity as an ensemble of code CFTs
Anatoly Dymarsky, Johan Henriksson, Brian McPeak
We discuss the holographic correspondence between 3d "Chern-Simons gravity" and an ensemble of 2d Narain code CFTs. Starting from 3d abelian Chern-Simons theory, we construct an en…

Positivity Bounds on Massive Vectors
Francesco Bertucci, Johan Henriksson, Brian McPeak +3
In this paper, we explore positivity bounds for the effective field theory~(EFT) of a single weakly coupled massive vector field. The presence of both mass and spin makes the cross…

Causality bounds from charged shockwaves in 5d
Sera Cremonini, Brian McPeak, Mohammad Moezzi +1
Effective field theories are constrained by the requirement that their constituents never move superluminally on non-trivial backgrounds. In this paper, we study time delays experi…
