Boundary Liouville CFT from the Bootstrap
Panos Betzios, Paul Ghiringhelli, Olga Papadoulaki +1
We construct boundary Liouville conformal field theory at central charge with FZZT-type boundary conditions and show that it satisfies the Cardy--Lewellen sewing constrain…
Before the Bang: Wormholes at the Dawn of the Universe
Panos Betzios, Paul Ghiringhelli, Ioannis D. Gialamas +1
This essay discusses recent progress on Euclidean wormholes as candidate contributions to the Universe's initial quantum state. The comparison with the Hartle-Hawking no-boundary p…
A Menagerie of Wormholes and Cosmologies in the Gravitational Path Integral
Panos Betzios, Paul Ghiringhelli, Ioannis D. Gialamas +1
We analyse a variety of Euclidean saddles in the gravitational path integral, with asymptotic AdS boundary conditions, in a class of Einstein-Scalar-Maxwell models. These include s…
