FLEET collaboration traps light–matter particles FLEET’s Research theme 2 seeks to create near-zero resistance flow of exciton polaritons, which are hybrid quasi-particles that are part matter and part light. Their ability to flow without resistance relies on formation of an exciton-polariton condensate – a collective quantum state that behaves as a superfluid. In superfluids, particles flow without encountering any resistance …
