Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate

In Bose-Einstein condensates, spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behavior, shows periodic density modulation typical for crystals. Here, we report the fabrication of an original type of optical...
