A ‘pumped’ laser can be used to trap and manipulate an exciton-polariton condensate. These quantum fluids, which can behave as a resistanceless superfluid in certain conditions, need continuous replenishing, with the pumping laser supplying both a reservoir of electrons and confining force. “The pumping laser can trap the quantum fluid as the particles are repelled from the pump region, similarly …
