‘Demon’ particle found in superconductor could explain how they work

A mysterious particle has been found inside a superconducting crystal, greater than 60 years after it was first predicted. The particle, known as Pines’s demon, could explain why some supplies superconduct, that means they have zero electrical resistance, and assist information the seek for new superconducting supplies.

The particle is a sort of plasmon, so-called as a result of it arises from a group of charged particles known as a plasma. Such plasmas can kind when electrons float freely from an atom, like in metallic supplies. Plasmons are …
