Ramp and plateau in bulk correlators within the disk topology in JT gravity
Cristiano Germani, Mickael Komendyak
We study bulk two-point correlation functions of a massless scalar field in Jackiw-Teitelboim gravity around the eternal black hole saddle. While same-side correlators exhibit expo…

A novel approach to cosmological particle production
Bartomeu Fiol, Mickael Komendyak, Jordi Ruiz-Ponsell
In this work we present a novel approach to the study of cosmological particle production in asymptotically Minkowski spacetimes. We emphasize that it is possible to determine the…
