Our paper on metastable condensation of exciton-polaritons in a Kagome lattice was published today.  This experimental paper discusses the effects of putting an exciton-polariton condensate inside a Kagome lattice structure, created by a periodic array of metal traps deposited on the surface.  As has been observed with other lattice geometries, it causes metastable condensation in the excited bands.  For the Kagome lattice there are some interesting effects such as a flat band structure, originating from localized states caused not from interaction, but from interference through the lattice.

 

The white areas in (c) above show condensation in the high orbital bands.
