Nonequilibrium Phase Transitions and Single-Photon Interaction Dynamics in Rydberg Atoms
Prof. Jin-Hui Wu
Center for Quantum Sciences, Northeast Normal University, China

Rydberg atoms have attracted extensive attentions in recent years due to exaggerated properties like long lifetimes and strong interactions. They are shown in theory and experiment to promise a versatile platform for quantum information processing and quantum many-body simulation. Here we briefly review a few important advances on nonequilibrium phase transitions due to collective quantum jumps, exotic interaction dynamics between single-photon pulses, and phase gate strategies based on single-photon storage using cold or thermal Rydberg atoms. We also introduce one of our recent works by presenting an efficient approach with a set of nonlocal potentials to simulate the propagation dynamics of interacting single-photon pulses in a Rydberg atomic ensemble. Our full dynamical calculations show some unexpected results lacked in previous works where more approximations are adopted to overcome the complexity in many-body systems.
