Controlled Ordering of Topological Charges in an Exciton-Polariton Chain
We demonstrate, experimentally and theoretically, controlled loading of an exciton-polariton vortex chain into a 1D array of trapping potentials. Switching between two types of vortex chains, with topological charges of the same or alternating signs, is achieved by appropriately shaping an off-resonant pump beam that drives the system to the regime of bosonic condensation. In analogy to spin chains, these vortex sequences realize either a “ferromagnetic” or an “antiferromagnetic” order, whereby...[Show more]
