Researchers from the Skolkovo Institute of Science and Technology and scientists from the UK have successfully solved
As the study authors note, polaritonsrepresent a successful “sandbox” for studying complex natural phenomena. For example, scientists managed to create a system that has common elements with a radiating black hole.
Polaritons themselves are compositequasiparticles arising from the interaction of photons with elementary excitations of the medium - optical phonons, excitons, plasmons, magnons, and so on.
Scientists have long wondered about...Is it possible to use polaritons to form such an exotic quantum object as a stable giant vortex. Until now, attempts to create such a “tornado” have been unsuccessful. The problem is that it very quickly fell apart. In their work, Russian and British physicists clearly showed that the problem of instability is not typical for quantum funnels inside polariton condensates.
The authors of the study hope that such experiments with quantum funnels will lead scientists to the creation of, for example, lasers with unique characteristics and new optoelectronic devices.
