The holy grail of superconductivity!
"Graphene can be made to superconduct by placing it next to a Bose-Einstein condensate – a form of matter in which all the atoms are in the same quantum state. ... this new type of superconductivity stems from interactions between the electrons in graphene and quasiparticles called “bogolons” in the condensate. ... “In this case, we can achieve robust, relatively high-temperature superconductivity,” ... [researcher] team calculated a superconducting transition temperature of 70 K. ..."
"We propose a mechanism for robust Bardeen–Cooper–Schrieffer-like superconductivity in graphene placed in the vicinity of a Bose–Einstein condensate. Electrons in the graphene interact with the excitations above the condensate, called Bogoliubov quasiparticles (or bogolons). It turns out that bogolon-pair-mediated interaction allows us to surpass the long-standing problem of the vanishing density of states of particles with a linear spectrum. This results in a dramatic enhancement of the superconducting properties of graphene while keeping its relativistic dispersion. ..."
