The Russian scientist proved the theoretical possibility of superconductivity at room temperature

The classical theory of superconductivity (aka BCS theory) allowed the possibility of this phenomenon only at temperatures only a few degrees above absolute zero. However, superconductors operating at a temperature of -70 degrees Celsius have already been obtained. For a comfortable and thoughtful work with such materials physicists need theoretical foundations that would be consistent with the actual behavior of superconductors.

The Russian scientist proved the theoretical possibility of superconductivity at room temperature

The most promising theory for explaining superconductivity is the bipolaron theory. According to it, superconductivity is explained by transitions of the ideal three-dimensional Bose condensate (the aggregate state of matter, which is based on bosons) of translationally invariant bipolarons. The scientist Victor Lakhno of the Institute of Applied Mathematics added to this theory the “missing link”, proving that the Bose condensate can be formed from a quantum Bose gas; The latter, in turn, consists of the same TI-bipolarons.

The bipolaron is a particle consisting of two conduction electrons that move in the crystal and are connected through a strong interaction with the medium. Victor Lakhno managed to theoretically prove that bipolaron can be a plane wave in the crystal lattice, and that TI-bipolarons can form a stable Bose condensate even at room temperature.

The work of the scientist, published in Advances in Condensed Matter Physics, opens new perspectives in the creation of indoor superconductors. It became clear that for the transition to the state of superconductivity, all electrons of the material should not be paired. It is enough only to increase the concentration of TI-bipolarons to a certain level.
