Gravitational Observatories
Dionysios Anninos, Damián A. Galante, Chawakorn Maneerat
We consider four-dimensional general relativity with vanishing cosmological constant defined on a manifold with a boundary. In Lorentzian signature, the timelike boundary is of the…
dS Supergravity
Dionysios Anninos, Pietro Benetti Genolini, Beatrix Mühlmann
We construct two-dimensional supergravity theories endowed with a positive cosmological constant, that admit de Sitter vacua. We consider the cases of as well as $\…
The Discreet Charm of the Discrete Series in DS
Dionysios Anninos, Tarek Anous, Ben Pethybridge +1
We study quantum field theories placed on a two-dimensional de Sitter spacetime (dS) with an eye on the group-theoretic organisation of single and multi-particle states. We exp…
