quasiparticles (such as exciton-polaritons and magnons), and even photons in a cavity. BECs behave as superfluids, meaning they can flow without friction. This property arises from the coherent nature ...

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate ...
