Carroll-Cotton Tensors and Gravitational Radiation at Null Infinity
Adrien Fiorucci, Simon Pekar, P. Marios Petropoulos +1
We provide a first-principles definition of Cotton tensors on conformal Carroll geometries by gauging the conformal Carroll algebra. On the mathematical side, this analysis yields…
The thermal representation of conformal ladder integrals
Manthos Karydas, Songyuan Li, Anastasios C. Petkou +1
We present the details of a recently discovered representation of conformal four-point ladder integrals as thermal one-point functions in scalar field theories. We show that the co…
Carrollian-holographic Derivation of Gravitational Flux-Balance Laws
Adrien Fiorucci, Simon Pekar, P. Marios Petropoulos +1
We demonstrate that the BMS evolution equations for the mass and angular momentum aspects in asymptotically flat Einstein gravity follow from local Carroll, Weyl, and diffeomorphis…
Conformal graphs as twisted partition functions
Manthos Karydas, Songyuan Li, Anastasios C. Petkou +1
We show that a class of -loop conformal ladder graphs correspond to twisted partition functions of free massive complex scalars in dimensions. The graphs arise as four-…
Flat from anti-de Sitter
Andrea Campoleoni, Arnaud Delfante, Simon Pekar +3
Ricci-flat solutions to Einstein's equations in four dimensions are obtained as the flat limit of Einstein spacetimes with negative cosmological constant. In the limiting process,…
Ehlers, Carroll, Charges and Dual Charges
Nehal Mittal, P. Marios Petropoulos, David Rivera-Betancour +1
We unravel the boundary manifestation of Ehlers' hidden Möbius symmetry present in four-dimensional Ricci-flat spacetimes that enjoy a time-like isometry and are Petrov-algebraic.…
