One-directional Quantum Synchronization of Atomic Ensembles — •Alexander Roth and Klemens Hammerer — Institute for Theoretical Physics, Leibniz University Hannover

In the classical regime, as first demonstrated by Huygens, can coupled oscillators undergo phase-synchronization and it has been shown that two detuned ensembles of atoms coupled by a cavity show a similar synchronization, but in the quantum regime [1]. We are investigating if and how this effect emerges if the coupling of the two ensembles is one-directional. This coupling can be realized with the atom clouds in two separate, cascaded cavities creating a one-directional coupling between the cavities.
