Dear Quantizers, Stochastic Brane
Justin Kulp
Stochastic quantization formulates -dimensional Euclidean QFT as the equilibrium limit of a -dimensional Langevin system. Using the supersymmetric formulation of stochast…
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…
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…
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…
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…
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…
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…
Higher Operations in Perturbation Theory
Davide Gaiotto, Justin Kulp, Jingxiang Wu
We discuss the role of formal deformation theory in quantum field theories and present various ``higher operations'' which control their deformations, (generalized) OPEs, and anoma…
Semi-Chiral Operators in 4d Gauge Theories
Kasia Budzik, Davide Gaiotto, Justin Kulp +3
We discuss the properties of quarter-BPS local operators in four dimensional supersymmetric Yang-Mills theory using the formalism of holomorphic twists. We study loop…
Feynman Diagrams in Four-Dimensional Holomorphic Theories and the Operatope
Kasia Budzik, Davide Gaiotto, Justin Kulp +2
We study a class of universal Feynman integrals which appear in four-dimensional holomorphic theories. We recast the integrals as the Fourier transform of a certain polytope in the…
Notes on Resonances and Unitarity from Celestial Amplitudes
Diego García-Sepúlveda, Alfredo Guevara, Justin Kulp +1
We study the celestial description of the sigma model in the large limit as introduced by Coleman, Jackiw and Politzer. Focusing on three dimensions, we analyze the impl…
Duality Defects in
I. M. Burbano, Justin Kulp, Jonas Neuser
We classify all non-invertible Kramers-Wannier duality defects in the lattice Vertex Operator Algebra (i.e. the chiral WZW model) coming from symmetr…
Orbifold groupoids
Davide Gaiotto, Justin Kulp
We review the properties of orbifold operations on two-dimensional quantum field theories, either bosonic or fermionic, and describe the "Orbifold groupoids" which control the comp…
Two More Fermionic Minimal Models
Justin Kulp
In this short note, we comment on the existence of two more fermionic unitary minimal models not included in recent work by Hsieh, Nakayama, and Tachikawa. These theories are obtai…
D-functions and immanants of unitary matrices and submatrices
Hubert de Guise, Dylan Spivak, Justin Kulp +1
Motivated by recent results in multiphoton interferometry, we expand a result of Kostant on immanants of an arbitrary unitary matrix su to the submatrices o…
