From Asymptotically Flat Gravity to Finite Causal Diamonds
Luca Ciambelli, Temple He, Kathryn M. Zurek
We demonstrate that the phase space of the soft sector of asymptotically flat gravity in four spacetime dimensions can be identified with that of a spherically symmetric finite cas…
Foundations of Carrollian Geometry
Luca Ciambelli, Puttarak Jai-akson
Carrollian physics provides the natural framework for describing null hypersurfaces. This review explores the geometry of Carrollian manifolds -- spaces endowed with a degenerate m…
Entanglement Entropy of Quantum Corners
Luca Ciambelli, Jerzy Kowalski-Glikman, Ludovic Varrin
In gravitational theories with boundaries, diffeomorphisms can become physical and acquire a non-vanishing Noether charge. Using the covariant phase space formalism, on shell of th…
Radiation in Fluid/Gravity and the Flat Limit
Gabriel Arenas-Henriquez, Luca Ciambelli, Felipe Diaz +2
We explore asymptotically locally anti-de Sitter spacetimes exhibiting gravitational radiative behavior, employing null gauges that allow for a well-defined flat limit. The radiati…
Quantum Area Fluctuations from Gravitational Phase Space
Luca Ciambelli, Temple He, Kathryn M. Zurek
We study the gravitational phase space associated to a stretched horizon within a finite-sized causal diamond in -dimensional spacetimes. By imposing the Raychaudhuri equati…
pychop: Emulating Low-Precision Arithmetic in Numerical Methods and Neural Networks
Erin Carson, Xinye Chen
Motivated by the growing demand for reduced-precision arithmetic in computational science, we exploit lower-precision emulation in Python{--}widely regarded as the dominant program…
Geometric modular flows in 2d CFT and beyond
Jacqueline Caminiti, Federico Capeccia, Luca Ciambelli +1
We study geometric modular flows in two-dimensional conformal field theories. We explore which states exhibit a geometric modular flow with respect to a causally complete subregion…
