They combine light and matter and create "hybrid" particles to help develop new technologies

Scientists at the University of Chicago (USA) have been able to create "hybrid" particles with new behaviors by combining light and matter, a discovery that can help create more powerful computers or quantum communications that are impossible to "hack" , according to a new study published this Wednesday in the journal Nature.

In particular, researchers have made light particles called photons to acquire a behavior similar to that of particles that form matter.

The photons do not have a table and are not inclined to face each other. However, physicists are able to change this characteristic by the photons merging into an atom and combining them with an electron. "In order for photons to collide with each other, we use atoms as intermediaries," said lead author of the study, Logan Clark.

This connection between electrons and photons forms a form A quasi-partial "hybrid" called polarithonIt can move quickly through space as light, but at the same time it has the ability to connect to other polaritons, allowing it to form an object.

However, physicists have to react only with photons with atoms that have very specific energies. To overcome this, researchers are using a new cloning technique for atoms that includes a laser that causes atoms to shake in the same way and produce similar energies.

The photons are then combined with these atoms to create Flocker's polaritons, some quasiparticles, which are part light and partial atom and unlike ordinary photons, they interact intensely with each other. In addition, they have a small amount of mass provided by the interaction of the electron and can be controlled.

"Flocke's polaritons are full of surprises, we still understand them better," Clark said. "Our next task will be to use these photons that collide to create topological light liquids. This is a very exciting time, "Clark added.
