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…

Holographic Fluctuation-Dissipation Relations in Finite Density Systems
Shivam K. Sharma
Using real-time holography, we investigate fluctuation-dissipation relations in holographic systems at finite density. In the bulk, it corresponds to the study of scattering of a c…

Open EFT for Interacting Fermions from Holography
Godwin Martin, Shivam K. Sharma
We initiate the study of an open EFT for finite-temperature holographic systems with interacting fermions. In particular, we do this for Yukawa interactions in the bulk using the r…
