Squashed Holography with Scalar Condensates
Gabriele Conti, Thomas Hertog, Yannick Vreys
We evaluate the partition function of the free and interacting O(N) vector model on a two-parameter family of squashed three spheres in the presence of a scalar deformation. We als…
Comments on Squashed-sphere Partition Functions
Nikolay Bobev, Pablo Bueno, Yannick Vreys
We study the partition function of odd-dimensional conformal field theories placed on spheres with a squashed metric. We establish that the round sphere provides a local extremum f…
Quantum Transitions Through Cosmological Singularities
Sebastian F. Bramberger, Thomas Hertog, Jean-Luc Lehners +1
In a quantum theory of cosmology spacetime behaves classically only in limited patches of the configuration space on which the wave function of the universe is defined. Quantum tra…
