Unitary quantum conformal Bondi-Metzner-Sachs field theories
Daniel Grumiller, Iva Lovrekovic
We impose unitarity constraints on two-dimensional field theories whose symmetries form the quantum conformal Bondi-Metzner-Sachs algebra, which combines conformal symmetries with…
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…
Boundary Carrollian CFTs and Open Null Strings
Arjun Bagchi, Pronoy Chakraborty, Shankhadeep Chakrabortty +3
We consider Carrollian conformal field theories in two dimensions and construct the boundary Carrollian conformal algebra (BCCA), opening up innumerable possibilities for further s…
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…
Carrollian c-functions and flat space holographic RG flows in BMS3/CCFT2
Daniel Grumiller, Max Riegler
We discuss c-functions and their holographic counterpart for two-dimensional field theories with Carrollian conformal fixed points in the UV and the IR. Specifically, we construct…
Carroll black holes
Florian Ecker, Daniel Grumiller, Jelle Hartong +3
Despite the absence of a lightcone structure, some solutions of Carroll gravity show black hole-like behaviour. We define Carroll black holes as solutions of Carroll gravity that e…
