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…
Operator thermalization vs eigenstate thermalization
Aleksandar Bukva, Philippe Sabella-Garnier, Koenraad Schalm
We study the characteristics of thermalizing and non-thermalizing operators in integrable theories as we turn on a non-integrable deformation. Specifically, we show that , an…
Thermalization/Relaxation in integrable and free field theories: an Operator Thermalization Hypothesis
Philippe Sabella-Garnier, Koenraad Schalm, Tereza Vakhtel +1
Free or integrable theories are usually considered to be too constrained to thermalize. For example, the retarded two-point function of a free field, even in a thermal state, does…
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…
