Quantum Synchronization in a Spin-1 System

POSTER

Abstract

Synchronization can be described as self-sustained oscillators phase-locked to a weak external driving field. These phenomena are abundant in nature as is evident from the synchronization of fireflies, wind turbines, and neuronal activity. Recently, extending synchronization into the quantum regime has attracted more and more attention, as there are still open questions on the impact of the quantum nature of the system on synchronization. We report our recent progress on a joint theory-experiment project, which aims to study quantum synchronization in laser-cooled spin-1 87Rb atoms. In our experiment, the initial limit-cycle state is generated by incoherently coupling the energy levels of the F=1 ground state manifold. Synchronization of the limit-cycle state can then be realized by coherent coupling these energy levels with probe and control beams. By turning on and off the control and probe beams sequentially, the probe beam is stored and retrieved from the F=1 87Rb atoms. Synchronization is expected to be carried out via the storage of the probe beam and can be read out experimentally through the retrieved probe beam.
