Three-particle mechanism for unconventional superconductivity with potential applications in moiré materials

A novel electronic mechanism for superconductivity is introduced, wherein pairing between two conduction electrons is mediated by the virtual motion of a third one originating from the valence band. Relying on interband polarization rather than singularities near the Fermi level, this mechanism bypa...
