New superconductors

Surprises to come

“New superconductors” refer to a wide variety of materials: they are often artificially synthesized in laboratory and they cannot be described with the “classical” BCS theory of superconductivity. The origin of their superconductivity is probably not the same as that of lead or mercury, especially as far as the process of two electrons forming a Cooper pair is concerned.

Temperature at which a material becomes superconducting depending on the year of discovery, J. Bobroff, LPSHowever, one needs to remain cautious: these materials are studied in great detail in laboratories and we still struggle to understand how they work. It is also quite likely that the list of these new superconductors will get longer and longer as years go by; and we do not know what to expect.
