Cosmic Clustering
Dionysios Anninos, Frederik Denef
We show that the late time Hartle-Hawking wave function for a free massless scalar in a fixed de Sitter background encodes a sharp ultrametric structure for the standard Euclidean…
Incompressible Fluids of the de Sitter Horizon and Beyond
Dionysios Anninos, Tarek Anous, Irene Bredberg +1
There are (at least) two surfaces of particular interest in eternal de Sitter space. One is the timelike hypersurface constituting the lab wall of a static patch observer and the o…
Static Patch Solipsism: Conformal Symmetry of the de Sitter Worldline
Dionysios Anninos, Sean A. Hartnoll, Diego M. Hofman
We show that the propagators of gravitons and scalar fields seen by a static patch observer in de Sitter spacetime are controlled by hidden SL(2,R) symmetries, at all frequencies.…
Higher Spin Realization of the dS/CFT Correspondence
Dionysios Anninos, Thomas Hartman, Andrew Strominger
We conjecture that Vasiliev's theory of higher spin gravity in four-dimensional de Sitter space (dS) is holographically dual to a three-dimensional conformal field theory (CFT) liv…
Hot Halos and Galactic Glasses
Dionysios Anninos, Tarek Anous, Jacob Barandes +2
We initiate a systematic study of the state space of non-extremal, stationary black hole bound states in four-dimensional N = 2 supergravity. Specifically, we show that an exponent…
Future Boundary Conditions in De Sitter Space
Dionysios Anninos, Gim Seng Ng, Andrew Strominger
We consider asymptotically future de Sitter spacetimes endowed with an eternal observatory. In the conventional descriptions, the conformal metric at the future boundary I^+ is def…
