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 sta…

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 represe…

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…

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 4…

A story of non-conformal branes: spindles, disks, circles and black holes

Mathieu Boisvert, Pietro Ferrero

We consider the -dimensional gauged supergravities arising as a consistent truncation of type II on , which are associated with the near-horizon limit of D-brane…
