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…
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…
