Carroll symmetry, dark energy and inflation
Jan de Boer, Jelle Hartong, Niels A. Obers +2
Carroll symmetry arises from Poincaré symmetry upon taking the limit of vanishing speed of light. We determine the constraints on the energy-momentum tensor implied by Carroll symm…
The Price of Curiosity: Information Recovery in de Sitter Space
Lars Aalsma, Watse Sybesma
Recent works have revealed that quantum extremal islands can contribute to the fine-grained entropy of black hole radiation reproducing the unitary Page curve. In this paper, we us…
Page Curve for an Evaporating Black Hole
Friðrik Freyr Gautason, Lukas Schneiderbauer, Watse Sybesma +1
A Page curve for an evaporating black hole in asymptotically flat spacetime is computed by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically solvable semi-class…
Non-Boost Invariant Fluid Dynamics
Jan de Boer, Jelle Hartong, Emil Have +2
We consider uncharged fluids without any boost symmetry on an arbitrary curved background and classify all allowed transport coefficients up to first order in derivatives. We assum…
Action Complexity for Semi-Classical Black Holes
Lukas Schneiderbauer, Watse Sybesma, Lárus Thorlacius
We adapt the complexity as action prescription (CA) to a semi-classical model of two-dimensional dilaton gravity and determine the rate of increase of holographic complexity for an…
First order non-Lorentzian fluids, entropy production and linear instabilities
Napat Poovuttikul, Watse Sybesma
In this note, we investigate linear instabilities of hydrodynamics with corrections up to first order in derivatives. It has long been known that relativistic (Lorentzian) first or…
