Quantum criticality and nonequilibrium dynamics on a Lieb lattice of Rydberg atoms
Mark R. Hirsbrunner, Milan KornjaÄa, Rhine Samajdar +9
Neutral-atom quantum simulators offer a promising approach to the exploration of strongly interacting many-body systems, with applications spanning condensed matter, statistical me…
Information Propagation in Rydberg Arrays via Analog OTOC Calculations
Goksu Can Toga, Siva Darbha, Ermal Rrapaj +2
Out-of-time-order correlators (OTOCs) are the main tool for probing quantum chaos and scrambling, and have become crucial probes in many areas of quantum computing. However, the me…
Observation of an anomaly in the statistics of Kibble-Zurek defects
