German physicists from University of Bonn managed to create a gas for the first time from extremely compressed light particles.

And the result of this experiment is not only incredible, but also confirms the central theories of quantum physics, and also serves as a starting point for creating even more accurate sensors with the ability to measure tiny forces.

Using the example given by the website Technological innovation By the way, gases compress very easily, just keep in mind that: “If you plug the tire pump outlet with your finger, you can still push the piston through most of its stroke. But it won’t work as well with liquids that don’t compress well.“

In this case, how gases are made up of atoms or molecules that can move at speeds that can oscillate in space, and how that resembles light. And now we come to photons, which, according to the theory, can also be interpreted as a gas, which makes it possible to compress their particles under special conditions.

This effect was something that physicists were able to achieve experimentally for the first time.

“To do this, we store particles of light in a small box of mirrors. The more photons we put in there, the denser the photon gas becomes,” explained Professor Julian Schmitt of the University of Bonn, whose team has already created the superphoton and is using it to create wells of light.

To understand a little about how this light gas was created, you need to pay attention to the general rule: the denser the gas, the more difficult it is to compress. In order for physicists to compress light, they had to put photons in a mirror box. But the more photons you put in that box, the harder it became to compress your particles.

So it was until the photons, having reached a certain density, their particles ceased to resist and changed dramatically, allowing them to be compressed further without any resistance.

It was at this point that they realized that this change in behavior was due to the rules of quantum mechanics, where a particle of light has a “fuzziness” and as they get closer to each other, they begin to overlap. What physicists also call “quantum degeneracy”.

To reach this definition, the researchers had to face some obstacles, the first of which was the creation of a gas with variable particles and a certain temperature. That a warm bath was needed for this ”:“We insert molecules into the mirror box that can absorb photons,” Schmitt explained. – Subsequently, they emit new photons, which, on average, have a temperature of molecules – in our case, a little less than 300 Kelvin, which approximately corresponds to room temperature. . . . The second obstacle was that photon gases are not uniformly dense.

“We put molecules in a box with a mirror that can absorb photons,” Schmitt explained. “Subsequently, they emit new photons, which, on average, have the temperature of the molecules – in our case, just under 300 Kelvin, which is approximately room temperature.”

With this new advance, researchers now claim that quantum compressibility gas can still be improved, which will allow to create sensors that are even more capable of measuring the smallest forces.
