Static sphere observers and geodesics in Schwarzschild-de Sitter spacetime
Mir Mehedi Faruk, Edward Morvan, Jan Pieter van der Schaar
We analyze null- and spacelike radial geodesics in Schwarzschild-de Sitter spacetime connecting two conjugate static sphere observers, i.e. free-falling observers at a fixed radius…
Action, entropy and pair creation rate of charged black holes in de Sitter space
Edward K. Morvan, Jan Pieter van der Schaar, Manus R. Visser
We compute and clarify the interpretation of the on-shell Euclidean action for Reissner-Nordström black holes in de Sitter space. We show the on-shell action is minus the sum of th…
On the Euclidean Action of de Sitter Black Holes and Constrained Instantons
Edward K. Morvan, Jan Pieter van der Schaar, Manus R. Visser
We compute the on-shell Euclidean action of Schwarzschild-de Sitter black holes, and take their contributions in the gravitational path integral into account using the formalism of…
Shocks and Information Exchange in de Sitter Space
Lars Aalsma, Alex Cole, Edward Morvan +2
We discuss some implications of recent progress in understanding the black hole information paradox for complementarity in de Sitter space. Extending recent work by two of the auth…
Lessons on Eternal Traversable Wormholes in AdS
Ben Freivogel, Victor Godet, Edward Morvan +2
We attempt to construct eternal traversable wormholes connecting two asymptotically AdS regions by introducing a static coupling between their dual CFTs. We prove that there are no…
