Suggestions of decreasing dark energy from supernova and BAO data: an update
Mark Van Raamsdonk, Chris Waddell
In a previous work 2305.04946, we found that supernova and baryon acoustic oscillation data support the hypothesis that late time cosmic acceleration is caused by the potential ene…
Holographic motivations and observational evidence for decreasing dark energy
Mark Van Raamsdonk, Chris Waddell
Negative lambda gravitational effective field theories dual to holographic CFTs have potentially realistic cosmological solutions. Generic cosmological solutions of these effective…
Suggestions of decreasing dark energy from supernova and BAO data
Mark Van Raamsdonk, Chris Waddell
The potential energy from a time-dependent scalar field provides a possible explanation for the observed cosmic acceleration. In this paper, we investigate how data from supernova…
Accelerating cosmology from gravitational effective field theory
Stefano Antonini, Petar Simidzija, Brian Swingle +2
A large class of cosmologies have big-bang / big crunch spacetimes with time-symmetric backgrounds and asymptotically AdS Euclidean continuations suggesting a possible holog…
Bottom-up holographic models for cosmology
Chris Waddell
In this note, we investigate some simple generalizations of a bottom-up holographic approach to cosmology introduced in arXiv:1810.10601. Our models utilize the Karch/Randall/Takay…
Finding in 2+1 dimensional SCFT physics
Mark Van Raamsdonk, Chris Waddell
We study solutions of type IIB string theory dual to supersymmetric Yang-Mills theory on half of coupled to holographic three-dimensional superconfo…
Looking for (and not finding) a bulk brane
Wyatt Reeves, Moshe Rozali, Petar Simidzija +3
When does a holographic CFT with a boundary added to it (a BCFT) also have a `good' holographic dual with a localized gravitating end-of-the-world brane? We argue that the answer t…
Holographic and Localization Calculations of Boundary F for SUSY Yang-Mills Theory
Mark Van Raamsdonk, Christopher Waddell
Supersymmetric Yang-Mills (SYM) theory can be defined on a half-space with a variety of boundary conditions preserving scale invariance and half of the original supe…
Information radiation in BCFT models of black holes
Moshe Rozali, James Sully, Mark Van Raamsdonk +2
In this note, following [arXiv:1905.08255, arXiv:1905.08762, arXiv:1908.10996], we introduce and study various holographic systems which can describe evaporating black holes. The s…
Black Hole Microstate Cosmology
Sean Cooper, Moshe Rozali, Brian Swingle +3
In this note, we explore the possibility that certain high-energy holographic CFT states correspond to black hole microstates with a geometrical behind-the-horizon region, modelled…
