Observables in Schrödinger CFTs: How Aliens Built the Pyramids
Mathieu Boisvert, Shehab Hossam Fadda, Justin Kulp +1
We discuss the algebraic structure of observables in Schrödinger CFTs. These operators have zero mass (or particle number) and generically transform in staggered ''pyramid represen…
Where is tree-level heterotic string theory?
Mathieu Boisvert, Waltraut Knop, Leonardo Rastelli
We continue the tree-level S-matrix bootstrap program for quantum gravity, now in ten-dimensional theories with half-maximal supersymmetry. This setting includes the heterotic stri…
Revisiting Schrödinger CFTs: Factorization, Massless Particles, and a Path to the Bootstrap
Mathieu Boisvert, Shehab Hossam Fadda, Justin Kulp +1
We revisit Schrödinger CFTs from a modern point of view. We introduce the ''harmonic trap geometry,'' analogous to the cylinder picture in relativistic CFTs, and demonstrate a stat…
Cardy limit of the 3d superconformal index
Arash Arabi Ardehali, Mathieu Boisvert, Shehab Hossam Fadda
We study the superconformal index of 3d gauge theories in Cardy-like limits , extending techniques recently developed in the 4d…
