Brownian motion in a growing population of ballistic particles
Nathaniel V. Mon Père, Pierre de Buyl, Sophie de Buyl
We investigate the motility of a growing population of cells in a idealized setting: we consider a system of hard disks in which new particles are added according to prescribed gro…
Baby de Sitter Black Holes and dS/CFT
Sophie de Buyl, Stephane Detournay, Gaston Giribet +1
Unlike three-dimensional Einstein gravity, three-dimensional massive gravity admits asymptotically de Sitter space (dS) black hole solutions. These black holes present interesting…
Holography For a De Sitter-Esque Geometry
Dionysios Anninos, Sophie de Buyl, Stephane Detournay
Warped dS arises as a solution to topologically massive gravity (TMG) with positive cosmological constant and Chern-Simons coefficient in the region $μ^2 \ell…
Asymptotic symmetries of Schrödinger spacetimes
Geoffrey Compère, Sophie de Buyl, Stéphane Detournay +1
We discuss the asymptotic symmetry algebra of the Schrodinger-invariant metrics in d+3 dimensions and its realization on finite temperature solutions of gravity coupled to matter f…
G2 Dualities in D=5 Supergravity and Black Strings
Geoffrey Compère, Sophie de Buyl, Ella Jamsin +1
Five dimensional minimal supergravity dimensionally reduced on two commuting Killing directions gives rise to a G2 coset model. The symmetry group of the coset model can be used to…
Einstein billiards and overextensions of finite-dimensional simple Lie algebras
Thibault Damour, Sophie de Buyl, Marc Henneaux +1
In recent papers, it has been shown that (i) the dynamics of theories involving gravity can be described, in the vicinity of a spacelike singularity, as a billiard motion in a regi…
