Physicists have created a “tornado” in quantum matter from quasiparticles

Physicists for the first time managed to create stable giant vortices in a polariton condensate – exotic quantum matter from quasiparticles of polaritons.

Researchers from the Skolkovo Institute of Science and Technology and scientists from the UK have successfully solved the well-known problem of quantum hydrodynamics. In their work, they managed to create a stable giant vortex in interacting polariton condensates. The data obtained open up new possibilities for creating coherent light sources with a unique structure and research in the field of many-body theory under extreme conditions. The research results are published in the journal Nature Communications.

As the authors of the study note, polaritons are a good sandbox for studying complex natural phenomena. For example, scientists have succeeded in creating a system that shares common elements with a radiating black hole.

By themselves, polaritons are composite quasiparticles arising from the interaction of photons with elementary excitations of the medium – optical phonons, excitons, plasmons, magnons, and so on.

Scientists have long wondered if polaritons can be used 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 fell apart very quickly. In their work, Russian and British physicists have clearly shown 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.
