Seeing double: shock waves and the de Sitter horizon

Willy Fischler, Hare Krishna, Sarah Racz

We consider a de Sitter observer in his rest frame at late times who observes a particle slightly displaced from unstable equilibrium. Initially, the observer notices an axisymmetr…

There is more to the de Sitter horizon than just the area

Willy Fischler, Hare Krishna, Sarah Racz

It is well known that the area of the de Sitter cosmological horizon is related to the entropy of the bulk spacetime. Recent work has however shown that the horizon encodes more in…

Plato Meets de Sitter, or de Sitter's Allegory of the Cave

Willy Fischler, Sarah Racz

Configurations of masses located at the vertices of Platonic solids deep within the bulk of de Sitter spacetime generate deformations of the cosmological horizon with the geometry…

Generic ETH: Eigenstate Thermalization beyond the Microcanonical

Elena Cáceres, Stefan Eccles, Jason Pollack +1

The Eigenstate Thermalization Hypothesis (ETH) has played a key role in recent advances in the high energy and condensed matter communities. It explains how an isolated quantum sys…

One-half reflected entropy is not a lower bound for entanglement of purification

Josiah Couch, Phuc Nguyen, Sarah Racz +2

In recent work, Akers et al. proved that the entanglement of purification is bounded below by half of the -Rényi reflected entropy for all ,…

Scrambling in quantum cellular automata

Brian Kent, Sarah Racz, Sanjit Shashi

Scrambling is the delocalization of quantum information over a many-body system and underlies all quantum-chaotic dynamics. We employ discrete quantum cellular automata as classica…

Testing for relics of past strong buckling events in edge-on galaxies: Simulation predictions and data from SG

V. Cuomo, V. P. Debattista, S. Racz +7

The short-lived buckling instability is responsible for the formation of at least some box/peanut (B/P) shaped bulges, which are observed in most massive, , barred galaxies. N…

Speeding up the spread of quantum information in chaotic systems

Stefan Eccles, Willy Fischler, Tyler Guglielmo +2

We explore the effect of introducing mild nonlocality into otherwise local, chaotic quantum systems, on the rate of information spreading and associated rates of entanglement gener…
