Flat band polaritons spotted in Lieb lattice
A lattice of semiconductor pillars that supports the conduction of polariton quasiparticles has been created by physicists at ITMO University in St Petersburg, Russia and the University of Sheffield. This research was enabled by the excellent microcavity samples grown by Dr Edmund Clarke in the National Epitaxy Facility.
