Hot halos and galactic glasses (carbonado)
(2012-02-27)We initiate a systematic study of the state space of non-extremal, stationary black hole bound states in four-dimensional N = 2 supergravity. Specifically, we show that an exponential multitude of classically stable \halo" ... -
A de Sitter hoedown
(2010-12-01)Rotating black holes in de Sitter space are known to have interesting limits where the temperatures of the black hole and cosmological horizon are equal. We give a complete description of the thermal phase structure of all ... -
Inside out: meet the operators inside the horizon. On bulk reconstruction behind causal horizons
(2018-01-01)Based on the work of Heemskerk, Marolf, Polchinski and Sully (HMPS), we study the reconstruction of operators behind causal horizons in time dependent geometries obtained by acting with shockwaves on pure states or thermal ... -
A general definition of $JT_a$ -- deformed QFTs

Areas and entropies in BFSS/gravity duality
(2020-04-01)The BFSS matrix model provides an example of gauge-theory / gravity duality where the gauge theory is a model of ordinary quantum mechanics with no spatial subsystems. If there exists a general connection between areas and ... -
Density matrices in quantum gravity

An invitation to the principal series
(2020-09-01)Scalar unitary representations of the isometry group of d-dimensional de Sitter space SO(1, d) are labeled by their conformal weights ∆. A salient feature of de Sitter space is that scalar fields with sufficiently large ... -
OPE statistics from higher-point crossing

Disordered quivers and cold horizons
(2016-12-01)We analyze the low temperature structure of a supersymmetric quiver quantum mechanics with randomized superpotential coefficients, treating them as quenched disorder. These theories describe features of the low energy ... -
Black hole collapse in the 1/c expansion
(2016-07-01)We present a first-principles CFT calculation corresponding to the spherical collapse of a shell of matter in three dimensional quantum gravity. In field theory terms, we describe the equilibration process, from early times ... -
Mini-BFSS matrix model in silico
(2019-09-23)We study a mass-deformed N=4 version of the Banks-Fischler-Shenker-Susskind (BFSS) matrix model with three matrices and gauge group SU(2). This model has zero Witten index. Despite this, we give numerical evidence for the ... -
From conformal blocks to path integrals in the Vaidya geometry
(2017-09-01)Correlators in conformal field theory are naturally organized as a sum over conformal blocks. In holographic theories, this sum must reorganize into a path integral over bulk fields and geometries. We explore how these two ... -
Marginal deformations & rotating horizons
(2017-12-01)Motivated by the near-horizon geometry of four-dimensional extremal black holes, we study a disordered quantum mechanical system invariant under a global SU(2) symmetry. As in the Sachdev-Ye-Kitaev model, this system ... -
Parity and the modular bootstrap
(2018-09-01)We consider unitary, modular invariant, two-dimensional CFTs which are invariant under the parity transformation P. Combining P with modular inversion S leads to a continuous family of fixed points of the SP transformation. ... -
