| contents | 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 real-time formalism (grSK geometry). From the bulk perspective, this study corresponds to Yukawa scattering against a black hole, incorporating the effects of Hawking radiation. We derive an EFT in the exterior of the black hole and thus develop a Witten diagrammatic understanding of the scattering processes. This allows the explicit evaluation of boundary Schwinger-Keldysh (SK) correlators to arbitrary order, at tree-level in the bulk. Here we present explicitly the SK generating functional up to four-point functions. Finally, we represent the correlators in a column-vector representation that manifests microscopic unitarity and thermality, with all the statistical factors neatly folded in. |
