Russian physicist figured out how to create a “room” superconductor

MOSCOW, February 7 – RIA Novosti. Russian physicist, proved the possibility of the existence of superconductors working at room temperatures, having considered the unusual properties of one-dimensional defects that arise within them in the transition to the superconducting state, according to an article published in Springer Plus.

“Previously it was thought that superconductivity is possible only in the short stripes and long, it disappears, so the question of creating artificial stripes long length never occurred and was not raised. This study, by contrast, says that a high-temperature superconductor needs to include long stripes, which can be created using nanotechnology,” — said Viktor Lakhno Institute of mathematical problems of biology RAS, Pushchino, whose words the press service of the institution.

As the scientist explains, in recent years physicists have discovered or created some types of superconductors that can work at very high temperatures, which in the best cases only reaches minus 70 degrees Celsius, which is almost attainable in natural conditions. Their appearance demanded a new explanation of how such structures are able to conduct current without visible loss, despite the fact that they “violate” the first foundations of the theory of superconductivity, formulated in the late 50 years.

Unusual properties of new superconductors, according Lakhno, due to the fact that scientists believe that they represent not be inside three-dimensional, and a kind of two-dimensional or even one-dimensional material that consists of a special quasiparticle-the polaron and which behaves as a so-called “condensate Bose-Einstein”.

It represents the unusual properties of liquid, which behaves as a single gigantic atom is “smeared” on a huge area, with certain properties have superconducting properties. The problem, according to physics was that scientists believed that the condensate Bose-Einstein may occur in one-dimensional or two-dimensional systems, since it denies the theory and calculations of academician Ginzburg.

Lakhno disagree, since his calculations show that the condensate Bose-Einstein, and superconductivity may exist within the so-called stripes – one-dimensional deformations of the crystal lattice of a substance, capable of being a superconductor, the transition to the superconducting state.

Moreover, the performed calculations show that such defects can exist at room temperature that shows that the “room” superconductors do you can create. According to Lahno, now it is time to create such materials is transferred from the hands of theoretical physicists into the hands of practitioners – it is certain that nanoparticles and nanomaterials, in which defects in the crystal lattice will behave as desired, to create quite real.
