Causality violations in Lovelock theories

R Brustein, Y Sherf - Physical Review D, 2018 - APS
Higher-derivative gravity theories, such as Lovelock theories, generalize Einstein's general
relativity (GR). Modifications to GR are expected when curvatures are near Planckian and …

Warped AdS3 black holes in higher derivative gravity theories

S Detournay, LA Douxchamps, GS Ng… - Journal of High Energy …, 2016 - Springer
A bstract We consider warped AdS 3 black holes in generic higher derivatives gravity
theories in 2+ 1 dimensions. The asymptotic symmetry group of the phase space containing …

Lovelock gravity is equivalent to Einstein gravity coupled to form fields

R Brustein, AJM Medved - Physical Review D—Particles, Fields, Gravitation …, 2013 - APS
Lovelock gravity is a class of higher-derivative gravitational theories for which the linearized
equations of motion have no more than two time derivatives. Here, it is shown that any …

Graviton -point functions for UV-complete theories in anti-de Sitter space

R Brustein, AJM Medved - Physical Review D—Particles, Fields, Gravitation …, 2012 - APS
We calculate graviton n-point functions in an anti-de Sitter black brane background for
effective gravity theories whose linearized equations of motion have at most two time …

Non-perturbative unitarity constraints on the ratio of shear viscosity to entropy density<? format?> in ultraviolet-complete theories with a gravity dual

R Brustein, AJM Medved - Physical Review D—Particles, Fields, Gravitation …, 2011 - APS
We reconsider, from a novel perspective, how unitarity constrains the corrections to the ratio
of shear viscosity η to entropy density s. We start with higher-derivative extensions of …

Black Holes & Radiative Degrees of Freedom of Thomas-Whitehead Gravity

TC Grover - 2024 - search.proquest.com
Abstract Thomas-Whitehead Gravity is a d-dimensional protectively invariant model of
gravity. This model incorporates additional fields D ab and Π a bc with the metric gab. These …

Gravitational entropy and thermodynamics away from the horizon

R Brustein, AJM Medved - Physics Letters B, 2012 - Elsevier
We define, by an integral of geometric quantities over a spherical shell of arbitrary radius, an
invariant gravitational entropy. This definition relies on defining a gravitational energy and …

Holographic aspects of black holes in chiral conformal field theories

LA Douxchamps - 2020 - escholarship.mcgill.ca
This thesis investigates holographic dualities for three-dimensional spacetimes. We first
consider warped dualities, which involve gravity in a deformed anti-de Sitter space that is …
