Real Time Correlations and Complexified Horizons
Akhil Sivakumar
We construct black hole saddles dual to real-time/Schwinger-Keldysh (SK) path integrals with arbitrary splits of the thermal density matrix generalizing the holographic SK prescrip…
Gravitational Edge Mode in Jackiw-Teitelboim Supergravity
Kyungsun Lee, Akhil Sivakumar, Junggi Yoon
We study the gravitational edge mode in the Jackiw-Teitelboim~(JT) supergravity on the disk and it BF formulation. We revisit the derivation of the finit…
Holography of information in massive gravity using Dirac brackets
Joydeep Chakravarty, Diksha Jain, Akhil Sivakumar
The principle of holography of information states that in massless gravity, it is possible to extract bulk information using asymptotic boundary operators. In our work, we study th…
The timbre of Hawking gravitons: an effective description of energy transport from holography
Temple He, R. Loganayagam, Mukund Rangamani +2
Planar black holes in AdS, which are holographically dual to compressible relativistic fluids, have a long-lived phonon mode that captures the physics of attenuated sound propagati…
Effective field theory of stochastic diffusion from gravity
Jewel K. Ghosh, R. Loganayagam, Siddharth G. Prabhu +3
Planar black holes in AdS have long-lived quasinormal modes which capture the physics of charge and momentum diffusion in the dual field theory. How should we characterize the effe…
Holographic KMS relations at finite density
R. Loganayagam, Krishnendu Ray, Shivam K. Sharma +1
We extend the holographic Schwinger-Keldysh prescription introduced in arXiv:1812.08785 to charged black branes, with a view towards studying Hawking radiation in these backgrounds…
Fermionic Open EFT from Holography
R. Loganayagam, Krishnendu Ray, Akhil Sivakumar
In this work we initiate the study of open effective field theories of fermions interacting with holographic baths. As a first step in this direction, we explain how the recently i…
Nonlinear Langevin dynamics via holography
Bidisha Chakrabarty, Joydeep Chakravarty, Soumyadeep Chaudhuri +3
In this work, we consider non-linear corrections to the Langevin effective theory of a heavy quark moving through a strongly coupled CFT plasma. In AdS/CFT, this system can be iden…
