String Theory and Superconducting Metals...

by Eugene Samuel Reich in Nature

"String theory, which some physicists hope may be able to unify gravity and quantum mechanics, may have found a real-world application. A type of black hole predicted by string theory may help to explain the properties of a mysterious class of materials called 'strange metals'.

"Strange metals include high-temperature superconductors, which have no electrical resistance at all below a critical temperature that is generally defined as above the boiling point of liquid nitrogen (−196 °C). Their properties have baffled condensed matter physicists for over 20 years because strange metals cannot be explained by the Fermi liquid model, which captures the properties of normal metals."
