Replication Regulates Volume Weighting in Quantum Cosmology
James Hartle, Thomas Hertog
Probabilities for observations in cosmology are conditioned both on the universe's quantum state and on local data specifying the observational situation. We show the quantum state…
A multitrace deformation of ABJM theory
Ben Craps, Thomas Hertog, Neil Turok
Motivated by the study of big crunch singularities in asymptotically spacetimes, we consider a marginal triple trace deformation of ABJM theory. The deformation corresponds…
The Classical Universes of the No-Boundary Quantum State
James B. Hartle, S. W. Hawking, Thomas Hertog
We analyze the origin of the quasiclassical realm from the no-boundary proposal for the universe's quantum state in a class of minisuperspace models. The models assume homogeneous,…
From Big Crunch to Big Bang with AdS/CFT
Neil Turok, Ben Craps, Thomas Hertog
The AdS/CFT correspondence is used to describe five-dimensional cosmology with a big crunch singularity in terms of super-Yang-Mills theory on R times S^3 deformed by a potential w…
The No-Boundary Measure of the Universe
James B. Hartle, S. W. Hawking, Thomas Hertog
We consider the no-boundary proposal for homogeneous isotropic closed universes with a cosmological constant and a scalar field with a quadratic potential. In the semi-classical li…
Violation of Energy Bounds in Designer Gravity
Thomas Hertog
We continue our study of the stability of designer gravity theories, where one considers anti-de Sitter gravity coupled to certain tachyonic scalars with boundary conditions define…
