Electronic Mechanism of Superconductivity in the Cuprates, C$_{60}$, and Polyacenes

摘要: On the basis of an analysis theoretical and numerical studies model systems experiments on superconductivity in doped ${\mathrm{C}}_{60},$ polyacenes, cuprate high-temperature superconductors, we propose that a purely electronic mechanism requires structures at intermediate scale or mesoscale. Specifically, address crucial question how superconducting pairing mesoscale can arise from repulsive interactions.
