Quantum dynamics, scars, and integrability in constrained Rydberg systems — •Vedika Khemani1, Christopher Laumann2, and Anushya Chandran2 — 1Harvard University, Cambridge, Massachusetts, USA — 2Boston University, Boston, Massachusetts, USA
A recent experiment on a 51-atom chain of Rydberg atoms observed anomalously long-lived temporal oscillations of local observables after quenching from an antiferromagnetic initial state. This coherence is surprising as the initial state should have thermalized rapidly to infinite temperature. I will describe the novel dynamics of this system using various diagnostics, and provide some insights into the underlying causes for the unusual dynamical properties of this system.
