The two-dimensional disordered sigma model
Martà Berenguer, Felix M. Haehl, Elisa Tabor
We introduce a two-dimensional nonlinear sigma model with random Gaussian -body interactions. The model combines the structure of a two-dimensional bosonic SYK-type quant…
A note on the quantization of angular momentum for black holes
Jon Goker, Luca V. Iliesiu, Elisa Tabor
We argue that the gravitational path integral for rotating black holes is periodic in the angular velocity, implying the quantization of angular momentum in arbitrary dimensions fo…
3D Gravity and Chaos in CFTs with Fermions
Jan Boruch, Elisa Tabor, Gustavo J. Turiaci
Pure 3d gravity in AdS is believed to admit a holographic description in terms of 2d CFT. We introduce a theory of fermionic 3d gravity where we sum over geometries equipped with s…
The algebraic structure of gravitational scrambling
Geoff Penington, Elisa Tabor
We introduce a new algebraic framework to describe gravitational scrambling, including the semiclassical limit of any out-of-time-order correlation function that is built out of op…
Discrete Max-Focusing
Raphael Bousso, Elisa Tabor
The Quantum Focusing Conjecture (QFC) lies at the foundation of holography and semiclassical gravity. The QFC implies the Bousso bound and the Quantum Null Energy Condition (QNEC).…
Simple Holography in General Spacetimes
Raphael Bousso, Elisa Tabor
The simple or "outermost" wedge in AdS is the portion of the entanglement wedge that can be reconstructed with sub-exponential effort from CFT data. Here we furnish a definition in…
