Order from chaos: taming quantum gravity with quantum chaos

27 Jun 2023

Our member Julian Sonner (UNIGE) receives SNSF Project funding for the project: Order from chaos: taming quantum gravity with quantum chaos from 01.06.2023 – 31.05.2027

Summary:

"As has been appreciated in recent years, the underlying microscopic dynamics of gravity exhibit all the hallmarks of highly chaotic systems, whether it be it in terms of an extremely sensitive dependence on initial condition, or the highly characteristic imprints on the spectra implied by hard quantum chaos.

In this project we explore the manifestations of these chaotic signatures in gravitational theories, aiming to move away from lower-dimensional “toy models” towards higher-dimensional examples and realistic boundary asymptotics. These signatures promise to elucidate questions that concern the conceptual foundations of quantum gravity itself, including whether spacetime at microscopic scales is given in terms of topologically non-trivial fluctuation in order to encode the chaotic level statistics alluded to above, and whether low-energy observers actually experience an ensemble-averaged version of the a microscopic theory, as would be natural in a quantum-chaotic system."
