"Quantum mechanics normally shows its influence only for tiny particles at ultralow temperatures, but the team mixed electrons with light to synthesise supersized quantum particles the thickness of a human hair, that behave like superconductors.
Building microscopic cavities which tightly trap light into the vicinity ofelectrons within the chip, they produced new particles called ‘polaritons’ which weigh very little, encouraging them to roam widely.
Dr. Gab Christmann working with Professor Jeremy Baumberg and Dr. Natalia Berloff of the University of Cambridge, together with a team in Crete, produced the special new samples needed which allow the polaritons to flow around at will without getting stuck.
Injecting them in two laser spots, they found that the resulting quantum fluid spontaneously started oscillating backwards and forwards, in the process forming some of the most characteristic quantum pendulum states known to scientists, but thousands of times larger than normal.
Dr. Christmann added: “This is not something we ever expected to see directly, and it is miraculous how mirror-perfect our samples have to be.We can steer our rivers of polariton quantum liquid on the fly by scanning around the laser beams that create them.”
