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…
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…
Bubbling wormholes and matrix models
Panos Betzios, Ji Hoon Lee, Olga Papadoulaki +1
The thermofield double state entangles two copies of a CFT via a sum over energy eigenstates and is dual to the two-sided eternal black hole. We explore an analogous construction u…
A microscopic Normal Matrix Model for
Panos Betzios
We describe the duality between the gravitating (compact) Sine-Gordon model and a normal matrix model. From a two-dimensional quantum gravity perspective and due to the perio…
Factorizations of 3d Interval Partition Functions
Boan Zhao, Panos Betzios, Paul Luis Roehl
We show that interval partition functions (transition amplitudes) of three- dimensional theories admit factorizations into sums of products of hemisphere partitio…
Magnetic Anti-de Sitter Wormholes as seeds for Higgs Inflation
Panos Betzios, Ioannis D. Gialamas, Olga Papadoulaki
We show how certain types of magnetic asymptotically Anti-de Sitter Euclidean wormholes can catalyze the onset of inflation. These wormholes can be embedded as saddle point solutio…
