Chaos and the Emergence of the Cosmological Horizon
David K. Kolchmeyer, Hong Liu
We construct algebras of diff-invariant observables in a global de Sitter universe with two observers and a free scalar QFT in two dimensions. We work in the strict $G_N \rightarro…

Toward stringy horizons
Elliott Gesteau, Hong Liu
We take a first step towards developing a new language to describe causal structure, event horizons, and quantum extremal surfaces (QES) for the bulk description of holographic sys…

New horizon symmetries, hydrodynamics, and quantum chaos
Maria Knysh, Hong Liu, Natalia Pinzani-Fokeeva
We generalize the formulation of horizon symmetries presented in previous literature to include diffeomorphisms that can shift the location of the horizon. In the context of the Ad…
