Quantum corrections to the near-extremal thermodynamics of (warped) BTZ black holes
Emilie Despontin, Stéphane Detournay, Robinson Mancilla +1
We study one-loop effects in the near-extremal thermodynamics of BTZ and warped BTZ black holes, with particular emphasis on the fate of eigenmodes that become zero modes in the ex…
Infinite-dimensional symmetries in plane wave spacetimes
Emilie Despontin, Stéphane Detournay, Dima Fontaine
We study the asymptotic symmetries of the Nappi-Witten spacetime in four dimensions, a plane wave arising as the Penrose limit of AdS. Imposing suitable boundary cond…
Universal sectors of two-dimensional Carrollian CFTs
Ankit Aggarwal, Arjun Bagchi, Stephane Detournay +3
We revisit modular invariance in two-dimensional Carrollian conformal field theories from a geometric perspective. Focusing on the characters of the induced and highest-weight repr…
Photon rings in a holographic toy model
Stéphane Detournay, Sahaja Kanuri, Alexandru Lupsasca +3
Light circling around an astrophysical black hole can spend a long time skirting its unstably bound photon orbits before escaping to infinity. To a distant observer, this orbiting…
Anisotropic conformal Carroll field theories and their gravity duals
Emilie Despontin, Stephane Detournay, Sudipta Dutta +1
We investigate anisotropic conformal Carroll field theories and their holographic duals. On the field theory side, we focus on the case with scaling exponent in two and three…
Asymptotic T-duality in three dimensions
Stéphane Detournay, José Figueroa, Alejandro Vilar López
In (super)gravity theories, T-duality relates solutions with an exact isometry which can have wildly different asymptotic behaviors: a well-known example is the duality between BTZ…
