Quantum Love Numbers are Non-Zero
Asaad Elkhidir, Godwin Martin, Julio Parra-Martinez +1
The static Love numbers of four-dimensional Schwarzschild black holes vanish classically. We show that this is not true in the quantum theory. Working in the worldline effective fi…
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…
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…
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…
