Gravitational Observatories in AdS
Dionysios Anninos, Raúl Arias, Damián A. Galante +1
We consider four-dimensional general relativity with a negative cosmological constant in the presence of a finite size boundary, , for both Euclidean and Lorentzian signature. A…
Remarks on 2D quantum cosmology
Dionysios Anninos, Chiara Baracco, Beatrix Mühlmann
We consider two-dimensional quantum gravity endowed with a positive cosmological constant and coupled to a conformal field theory of large and positive central charge. We study cos…
de Sitter at all loops: the story of the Schwinger model
Dionysios Anninos, Tarek Anous, Alan Rios Fukelman
We consider the two-dimensional Schwinger model of a massless charged fermion coupled to an Abelian gauge field on a fixed de Sitter background. The theory admits an exact solution…
Cosmological Observatories
Dionysios Anninos, Damián A. Galante, Chawakorn Maneerat
We study the static patch of de Sitter space in the presence of a timelike boundary. We impose that the conformal class of the induced metric and the trace of the extrinsic curvatu…
