Loops Outside a Black Hole
R. Loganayagam, Godwin Martin, Shivam K. Sharma
We present a general conjecture for evaluating multiple discontinuity integrals arising from bulk loop diagrams in the gravitational Schwinger-Keldysh geometry. This generalises ea…
Solvable Models of Heat Transport in Quantum Mechanics
R Loganayagam, Prithvi Narayan, Swathi T S
We investigate solvable models of heat transport between a pair of quantum mechanical systems initialized at two different temperatures. At time , a weak interaction is switch…
Influence Phase of a dS Observer II: Electromagnetism
R. Loganayagam, Omkar Shetye
We extend our proposal for static patch holography made in part I (arXiv:2309.07290) to the case of electromagnetism. Using the on-shell action on de Sitter Schwinger-Keldysh (dS-S…
An Exterior EFT for Hawking Radiation
R. Loganayagam, Godwin Martin
We present a general conjecture for evaluating the multiple-discontinuity integrals that appear in real-time holography using gravitational Schwinger-Keldysh (grSK) geometry. Our c…
