Cosmological Correlator Discontinuities from Scattering Amplitudes
Chandramouli Chowdhury, Sadra Jazayeri, Arthur Lipstein +3
Recent theoretical work has revealed that basic observables of quantum field theory in de Sitter space, known as in-in or cosmological correlators, exhibit surprisingly simple math…
On in-in correlators for spinning theories and their shadow formulation
Chandramouli Chowdhury, Arthur Lipstein, Joe Marshall +1
In-in correlators are the basic observables in cosmology and are traditionally computed using the Schwinger-Keldysh formalism. In this paper we revisit this formalism for photons,…
Cosmological Dressing Rules
Chandramouli Chowdhury, Arthur Lipstein, Joe Marshall +2
The basic observables in cosmology are known as in-in correlators. Recent calculations have revealed that in-in correlators in four dimensional de Sitter space exhibit hidden simpl…
Light-cone actions and correlators of self-dual theories in AdS
Chandramouli Chowdhury, George Doran, Arthur Lipstein +3
Self-dual Yang-Mills and Einstein gravity in Euclidean AdS are useful toy models because they can be described by simple scalar Lagrangians exhibiting a new manifestation of th…
Loops, Recursions, and Soft Limits for Fermionic Correlators in (A)dS
Chandramouli Chowdhury, Pratyusha Chowdhury, Radu N. Moga +1
Study of correlation functions in AdS/CFT and in-in correlators in de Sitter space often requires the computation of Witten diagrams. Due to the complexity of evaluating radial int…
Soft Limits of Gluon and Graviton Correlators in Anti-de Sitter Space
Chandramouli Chowdhury, Arthur Lipstein, Jiajie Mei +1
We derive formulae for the soft limit of tree-level gluon and graviton correlators in Anti-de Sitter space, which arise from Feynman diagrams encoding the Weinberg soft theorems in…
