Full Eigenstate Thermalization in Quantum Field Theory: Free Cumulants and Gravitational Scrambling

Ricardo Espíndola, Viktor Jahnke

Using thermal analyticity, we derive directional large-frequency bounds on the smooth functions entering full eigenstate thermalization in continuum quantum field theory. The stron…

The mini-Page Curve in Cosmology

Ricardo Espíndola, Shoichiro Miyashita

The black hole information paradox has motivated extensive study of how and when information escapes from evaporating black holes. Here we address the analogous question for cosmol…

Spectral Admissibility of Real Observers in Euclidean de Sitter Gravity

Ricardo Espíndola, Ahmed Farag Ali

The Euclidean de Sitter path integral contains the familiar phase associated with conformal negative modes. Maldacena's construction shows that a suitably included real observer ca…

Islands and traversable wormholes

Ricardo Espíndola, Viktor Jahnke, Keun-Young Kim

We study information recovery in black hole evaporation using traversable wormhole protocols in AdS Jackiw-Teitelboim gravity with matter fields coupled to an external bath. By…

Flow-geometry microstates

Ricardo Espíndola, Shoichiro Miyashita

We construct geometric microstates for a class of two-dimensional flow geometriesspacetimes that interpolate from an asymptotic AdS boundary to a dS static patch in the…

A teleportation protocol in Schwarzschild-de Sitter space

Sergio E. Aguilar-Gutierrez, Ricardo Espíndola, Edward K. Morvan-Benhaim

We propose a new information transfer protocol for de Sitter space, using black holes as energy reservoirs. We consider antipodal observers in pure de Sitter space in the Bunch-Dav…

The centaur-algebra of observables

Sergio E. Aguilar-Gutierrez, Eyoab Bahiru, Ricardo Espíndola

This letter explores a transition in the type of von Neumann algebra for asymptotically AdS spacetimes from the implementations of the different gravitational constraints. We denot…

Changing states in holography: From modular Berry curvature to the bulk symplectic form

Bartlomiej Czech, Jan de Boer, Ricardo Espíndola +3

We present a new perspective on bulk reconstruction using Berry phases in the boundary CFT. Our parallel transport of modular Hamiltonians is associated to a trajectory in the spac…

Islands in FRW Cosmologies

Ricardo Espíndola, Bahman Najian, Dora Nikolakopoulou

We search for candidate island regions in FRW cosmologies supported by radiation, cosmological constant , and non-zero spatial curvature. The radiation is assumed to be in a the…

Virasoro Entanglement Berry Phases

Jan de Boer, Ricardo Espíndola, Bahman Najian +3

We study the parallel transport of modular Hamiltonians encoding entanglement properties of a state. In the case of 2d CFT, we consider a change of state through action with a suit…

What's the Point? Hole-ography in Poincare AdS

Ricardo Espíndola, Alberto Guijosa, Alberto Landetta +1

In the context of the AdS/CFT correspondence, we study bulk reconstruction of the Poincare wedge of AdS via hole-ography, i.e., in terms of differential entropy of the dual CFT…

Cusp Anomalous dimension and rotating open strings in AdS/CFT

R. Espíndola, J. Antonio García

In the context of AdS/CFT we provide analytical support for the proposed duality between a Wilson loop with a cusp, the cusp anomalous dimension, and the meson model constructed fr…
