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…
Loop Corrected Supercharges from Holomorphic Anomalies
Kasia Budzik, Justin Kulp
We describe the loop corrections to supercharges in supersymmetric quantum field theories using the holomorphic twist formalism. We begin by reviewing the relation between supercha…
Do null defects dream of conformal symmetry?
Rajeev S. Erramilli, Justin Kulp, Fedor K. Popov
We initiate the study of null line defects in Lorentzian conformal field theories in various dimensions. We show that null lines geometrically preserve a larger set of conformal is…
Holographic Foliations: Self-Similar Quasicrystals from Hyperbolic Honeycombs
Latham Boyle, Justin Kulp
Discrete geometries in hyperbolic space are of longstanding interest in pure mathematics and have come to recent attention in holography, quantum information, and condensed matter…
Multiparticle States for the Flat Hologram
Justin Kulp, Sabrina Pasterski
We use the extrapolate dictionary to revisit the spectrum of operators in Celestial CFT. Under the Celestial CFT map, each state in the 4D Hilbert space should map to one in the 2D…
