It is increasingly important to understand the spatial dynamics of epidemics. While there are numerous mathematical models of epidemics, there is a scarcity of physical systems with sufficiently well-controlled parameters to allow quantitative model...

It is challenging to probe ergodicity breaking trends of a quantum many-body system when dissipation inevitably damages quantum coherence originated from coherent coupling and dispersive two-body interactions. Rydberg atoms provide a test bed to dete... Read More about Ergodicity breaking from Rydberg clusters in a driven-dissipative many-body system..

Giant microwave–optical Kerr nonlinearity via Rydberg excitons in cuprous oxide (2024)

Emergence of Synchronization in a Driven-Dissipative Hot Rydberg Vapor (2023)
Journal Article

We observe synchronization in a thermal (35-60 °C) atomic (Rb) ensemble driven to a highly excited Rydberg state (principle quantum number n ranging from 43 to 79). Synchronization in this system is unexpected due to the atomic motion; however, we sh... Read More about Emergence of Synchronization in a Driven-Dissipative Hot Rydberg Vapor.
