One-loop partition function of gravity with leaky boundary conditions
Daniel Grumiller, Romain Ruzziconi, Céline Zwikel
Leaky boundary conditions in asymptotically AdS spacetimes are relevant to discuss black hole evaporation and the evolution of the Page curve via the island formula. We explore the…
Logarithmic soft graviton theorems from superrotation Ward identities
Shreyansh Agrawal, Laura Donnay, Kevin Nguyen +1
Soft graviton theorems receive one-loop contributions that are logarithmic in the energy of the soft graviton, and which are closely related to tails of gravitational waveforms. We…
Symmetries and Charges in Weyl-Fefferman-Graham Gauge
Luca Ciambelli, Arnaud Delfante, Romain Ruzziconi +1
We investigate the asymptotic symmetries of three-dimensional AdS Einstein gravity in the Weyl-Fefferman-Graham gauge, which is a generalization of the Fefferman-Graham gauge induc…
Logarithmic Celestial Conformal Field Theory
Adrien Fiorucci, Daniel Grumiller, Romain Ruzziconi
We argue that the celestial conformal field theory exhibits patterns of a logarithmic conformal field theory. We uncover a Jordan block structure involving the celestial stress ten…
