Universal Prethermal Dynamics of Bose Gases Quenched to Unitarity

Understand

Understanding strongly correlated phases of matter, from the quark-gluon plasma to neutron stars, and in particular the dynamics of such systems, $e.g.$ following a Hamiltonian quench, poses a fundamental challenge in modern physics.

• Ultracold atomic gases are excellent quantum simulators for these problems, thanks to tuneable interparticle interactions and experimentally resolvable intrinsic timescales.
• In particular, they give access to the unitary regime where the interactions are as strong as allowed by quantum mechanics.
• Following years of experiments on unitary Fermi gases, unitary Bose gases have recently emerged as a new experimental frontier.
