Synchronization of Two Ensembles of Atoms via Quantum and Classical Channels — •Alexander Roth and Klemens Hammerer — Institute for Theoretical Physics, Leibniz University Hannover

We show synchronization in a system of two cascaded superradiant frequency detuned lasers and point out the differences to two superradiant ensembles of atoms in one cavity [1]. Furthermore we show that this synchronization does not rely on the quantum coupling between both lasers, but can be simulated using a classical channel. Additionally we show that the synchronization of two superradiant ensembles of atoms coupling to the same cavity mode can also be simulated using a classical coupling channel.
