So how does High Temperature Superconductivity work? Classical Superconducitivty is done by cooper pair and the BCS mechanism, what is the counterpart in High Temp SC? Can it reach room temperature?
Thanks for that link. That's interesting.DrDu said:P. W. Anderson thinks that HTC is essentially understood, see e.g.:

DrDu said:After more than 20 years there has to be some consensus at least on the basic facts and much must have been ruled out by experiment.

High temperature superconductivity refers to a phenomenon where certain materials can conduct electricity with zero resistance at temperatures higher than the boiling point of liquid nitrogen (77 K or -196°C). This is in contrast to conventional superconductors which require much lower temperatures, close to absolute zero, to exhibit superconducting behavior.
High temperature superconductivity is still not fully understood, but it is believed to occur due to the formation of Cooper pairs, which are pairs of electrons that act together to carry current with zero resistance. In high temperature superconductors, this pairing is thought to occur through vibrations in the crystal lattice, rather than through electron-phonon interactions as in conventional superconductors.
Some potential applications of high temperature superconductivity include more efficient power transmission, faster and more powerful electronic devices, and more sensitive and accurate sensors. Superconducting magnets made from high temperature superconductors can also be used in medical imaging, such as MRI machines, and in particle accelerators.
One of the main challenges in achieving high temperature superconductivity is finding materials that exhibit this behavior. While there are several known high temperature superconductors, they are often difficult and expensive to produce in large quantities. Another challenge is understanding the mechanism behind high temperature superconductivity, which could potentially lead to the discovery of new materials with even higher critical temperatures.
High temperature superconductivity has the potential to revolutionize many areas of technology, leading to more efficient and sustainable energy production and storage, faster and more powerful electronics, and more sensitive and accurate sensors. It could also have a significant impact on healthcare, through the development of more advanced medical imaging techniques and treatments. Ultimately, high temperature superconductivity has the potential to improve the quality of life for many people and contribute to technological advancements in various industries.
