Aspects of Closed Matricial Worlds
Dionysios Anninos, Samuel Brian
We investigate the Hilbert space structure for simple theories of gravity with on closed spatial sections. Our motivation ties to the presence of gravitational saddles in fou…
de Sitter Vacua & pUniverses
Jeremias Aguilera-Damia, Dionysios Anninos, Tarek Anous +2
We analyze a simple extension of the Schwinger model, which we refer to as the -Schwinger model, on a de Sitter background. In this theory, the charged massless fermions carry n…
dS Metamorphosis
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We study the Euclidean path integral of higher spin gravity on . Based on a one-loop analysis, we are led to a gluing formula expressing the path integral in terms of an…
The Stretched Horizon Limit
Dionysios Anninos, Damián A. Galante, Silvia Georgescu +2
We consider four-dimensional general relativity with a positive cosmological constant, , in the presence of a boundary, , of finite spatial size. The boundary is located near…
Fermionic fields of higher spin in de Sitter space
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We consider fermionic fields of higher spin on a four-dimensional de Sitter background. A particular emphasis is placed on the Rarita-Schwinger spin- case. Both massi…
Features of the Partition Function of a Universe
Dionysios Anninos, Chiara Baracco, Samuel Brian +1
We consider properties of the gravitational path integral, , of a four-dimensional gravitational effective field theory with at the quantum level. To leadi…
