<pre>Finnish scientists for the first time in the world were able to create a quantum ball lightning

Although mankind has observed the phenomenon of ball lightning for many centuries, there is still no single undeniable model of its work. And if you go from the other side, thought the Finnish scientists from the University of Aalto, to design something similar, and then to study its characteristics? They succeeded in obtaining in laboratory conditions a tiny version of the skyrmion, a quasiparticle that could become a platform for turning into a ball lightning or something more.

As a basis for the experiment, the Finns took the Bose-Einstein condensate, so supercooled that its atoms actually lost energy movement. The scientists selected a magnetic field with such parameters that when a spin on atoms in the center of the conditional model, a field with zero charge was formed. After that, the spins of the atoms around him unfolded and intertwined into the likeness of a single ring-like structure. This is a skyrmion, a quasiparticle, the existence of which was predicted back in 1962.

Then the experiments began, of which two important conclusions were drawn. First, the skyrmion can be moved and acted on, the ring never opens, as long as the special structure of the magnetic field acts. Secondly, to create such a field, two correctly matched oppositely circulating electric currents are sufficient. That is, in theory, the superstable electromagnetic node can originate from the discharge of ordinary lightning and remain existing by itself – as in the old legends.

The quasiparticle created by Finnish scientists has a quantum effect, it does not exist without the activation of its magnetic field. Plus the laboratory skyrmion is very tiny, to “real” ball lightning it is still growing and growing. But if scientists really succeed in obtaining such an object, and even in a manageable form, this would mean a breakthrough in plasma control technologies and a chance to create fundamentally new types of reactors.
