Quantum stochastic thermodynamics of macroscopic systems: an algebraic approach
Antoine Rignon-Bret, Cyril Elouard
We build a framework for the thermodynamics of macroscopic quantum systems. In contrast with approaches requiring access to the full density matrix, our framework relies on a coars…
Black hole thermodynamics at null infinity. Part 2: Open systems, Markovian dynamics and work extraction from non-rotating black holes
Antoine Rignon-Bret, Matthieu Vilatte
Black hole thermodynamics provides a unique setting in which general relativity, quantum field theory, and statistical mechanics converge. In semiclassical gravity, this interplay…
Black hole thermodynamics at null infinity. Part 1: Dual Generalized Second Law
Antoine Rignon-Bret, Matthieu Vilatte
The generalized second law (GSL) of black hole thermodynamics asserts the monotonic increase of the generalized entropy combining the black hole area and the entropy of quantum fie…
General covariance and boundary symmetry algebras
Antoine Rignon-Bret, Simone Speziale
In general relativity as well as gauge theories, non-trivial symmetries can appear at boundaries. In the presence of radiation some of the symmetries are not Hamiltonian vector fie…
Spatially local energy density of gravitational waves
Antoine Rignon-Bret, Simone Speziale
We propose a new set of BMS charges at null infinity, characterized by a super-translation flux that contains only the `hard' term. This is achieved with a specific corner improvem…
Black hole thermodynamic potentials for asymptotic observers
Antoine Rignon-Bret
The generalized second law states the total entropy of any closed system as the universe cannot decrease if we include black hole entropy. From the point of view of an asymptotic o…
