From the Wavefunction of the Universe to In-In-Correlators: A Perturbative Map to All Orders
Gonzalo A. Palma
Both the Wavefunction of the Universe and the Schwinger-Keldysh in-in formalism are central tools for analyzing primordial cosmological observables, such as equal-time correlation…

Schwinger-Keldysh Cosmological Cutting Rules
Francisco Colipí-Marchant, Gabriel Marin, Gonzalo A. Palma +1
In this work, we study the realisation of unitarity-based cutting rules for primordial cosmological correlators computed within the Schwinger-Keldysh path integral formalism. While…
