Holographic Cosmology at Finite Time
Goncalo Araujo-Regado, Ayngaran Thavanesan, Aron C. Wall
We investigate Cauchy Slice Holography in de Sitter spacetime. By performing a deformation of a (bottom-up) dS/CFT model, we obtain a holographic theory living on flat Cauchy…
Kosmic Field Theories: Towards Holographic Duals for Unitary String Cosmologies
Ayngaran Thavanesan, Aron C. Wall
Recent work on cosmological amplitudes has established reality conditions (derived from unitarity) for general particle-creation processes in flat FLRW cosmologies, in the Bunch-Da…
Bounding field excursions along null geodesics with applications to cosmology
Aidan Herderschee, Aron C. Wall
Scalar fields in theories of gravity often inhabit a moduli space of vacua, and coherent spatial or temporal variations in their expectation values can produce measurable gravitati…
A Background-Independent Closed String Action at Tree Level
Amr Ahmadain, Alexander Frenkel, Aron C. Wall
We propose an off-shell bosonic string action that removes the renormalization window constraint of [1]. To all orders in conformal perturbation theory, this action allows for defo…
The Cosmological CPT Theorem
Harry Goodhew, Ayngaran Thavanesan, Aron C. Wall
The CPT theorem states that a unitary and Lorentz-invariant theory must also be invariant under a discrete symmetry which reverses charge, time, and one spatial dire…
A New Covariant Entropy Bound from Cauchy Slice Holography
Ronak M Soni, Aron C. Wall
We begin an investigation of a new holographic covariant entropy bound (HCEB) in gravity. This bound arises from Cauchy slice holography, a recently proposed duality between the bu…
