Physicists have proposed that a hypothetical form of matter called "unparticles" may play a key role in mediating superconductivity—the ability of certain materials to conduct electricity with zero resistance.

Physicists James LeBlanc and Adolfo Grushin at the Max Planck Institute for the Physics of Complex Systems in Dresden (LeBlanc is now with the University of Michigan in Ann Arbor) have published a paper on their proposal of unparticle-mediated superconductivity in a recent issue of the New Journal of Physics.

"Understanding all forms of superconductivity remains one of the holy grails of modern physics," Grushin told Phys.org. "Proposing new ways of how this astonishing phenomena can emerge is of key importance to push the frontier of knowledge that deals with how materials can superconduct. By identifying how unparticles contribute to superconductivity, we open a new path to possibly finding unparticles, by looking for strange superconducting behavior. Moreover, the novelty and broadness of our approach can inspire other researchers to look for this new type of superconductivity in nature."
