Gravitational Wilson Lines in 3D de Sitter

Alejandra Castro, Philippe Sabella-Garnier, Claire Zukowski

We construct local probes in the static patch of Euclidean dS gravity. These probes are Wilson line operators, designed by exploiting the Chern-Simons formulation of 3D gravity…

A Cardy formula for off-diagonal three-point coefficients; or, how the geometry behind the horizon gets disentangled

Aurelio Romero-Bermúdez, Philippe Sabella-Garnier, Koenraad Schalm

In the AdS/CFT correspondence eternal black holes can be viewed as a specific entanglement between two copies of the CFT: the thermofield double. The statistical CFT Wightman funct…

Time dependence of entanglement entropy on the fuzzy sphere

Philippe Sabella-Garnier

We numerically study the behaviour of entanglement entropy for a free scalar field on the noncommutative ("fuzzy") sphere after a mass quench. It is known that the entanglement ent…

Emergent geometry of membranes

Mathias Hudoba de Badyn, Joanna L. Karczmarek, Philippe Sabella-Garnier +1

In work arXiv:1204.2788, a surface embedded in flat is associated to any three hermitian matrices. We study this emergent surface when the matrices are large, by constructing…

Inviolable energy conditions from entanglement inequalities

Nima Lashkari, Charles Rabideau, Philippe Sabella-Garnier +1

Via the AdS/CFT correspondence, fundamental constraints on the entanglement structure of quantum systems translate to constraints on spacetime geometries that must be satisfied in…

Mutual information on the fuzzy sphere

Philippe Sabella-Garnier

We numerically calculate entanglement entropy and mutual information for a massive free scalar field on commutative (ordinary) and noncommutative (fuzzy) spheres. We regularize the…

Entanglement entropy on the fuzzy sphere

Joanna L. Karczmarek, Philippe Sabella-Garnier

We obtain entanglement entropy on the noncommutative (fuzzy) two-sphere. To define a subregion with a well defined boundary in this geometry, we use the symbol map between elements…
