Observation of Anomalies in the Statistics of Kibble-Zurek Defects

ORAL

Abstract

We explore the counting statistics of defects in Kibble-Zurek experiments on long 1D Rydberg atom chains. Experiments on QuEra's neutral atom quantum simulator reveal an anomaly in the counting statistics of defects at long ramp times, precluding the universal validity for the model of defect formation by independent domain merging events. Numerical simulations on NERSC's Perlmutter confirm the experimental anomaly and suggest the connection between the observed anomalous counting statistics regime and non-critical coarsening dynamics. Our results show the potential of current quantum simulators to discover novel strongly correlated quantum phenomena.
