Superconductivity: The Next Revolution?

Superconductivity: Next Revolution The high temperature superconductor discovered in 1987 caused a revolution in science and technology. The discovery of superconductors, its impact on the progress of physics, and its practicality in today's industry is the subject of Professor Vidali's book Superconductivity: Next Revolution. The author explains thoroughly the concept of superconductivity, the discovery of traditional superconductivity, the interpretation of its global technical aspects, the utility of the current industry, and the future impact of field development.

Room temperature superconductivity is still elusive and exciting like the last century. Whether room temperature superconductors can be present is unknown, but the discovery of high temperature superconductors is a promising indicator of nontraditional and very useful quantum effects in totally unexpected substances.

In the superconducting material, when the temperature T is lower than the critical temperature Tc, superconducting characteristics are generated. The value of this critical temperature depends on the material. Conventional superconductors typically have a critical temperature of about 20 K to less than 1 K. For example, the critical temperature of solid mercury is 4.2 K. As of 2015, a high pressure of about 90 gigapascals is required, but the highest critical temperature of conventional superconductors is 203 K for H 2 S. The copper oxide superconductor can have a higher critical temperature: YBa 2 Cu 3 O 7 is one of the first discovered copper superconductors with a critical temperature of 92 K, mercury based copper It is known that the critical temperature of oxides exceeds 130 K. The interpretation of these high critical temperatures is not yet known

Superconductivity is a phenomenon in which the electromagnetic field appearing in some materials (called superconductors) is strictly zero and the flux field is released when it is cooled below the characteristic critical temperature. Dutch physicist Heike Kamerlingh Onnes discovered in Leiden on April 8, 1911. Like ferromagnetism and atomic beams, superconductivity is a quantum mechanical phenomenon. It is characterized by a Meissner effect, ie complete emission of magnetic field lines during the transition from the interior of the superconductor to the superconducting state. The appearance of Meissner effect suggests that superconductivity can not simply be understood as an idealization of complete conduction in classical physics.
