Abstract: | Copper oxides become superconductors rapidly upon doping with electron holes, suggesting a fundamental pairing instability.
The Cooper mechanism explains normal superconductivity as an instability of a fermi-liquid state, but high-temperature superconductors
derive from a Mott-insulator normal state, not a fermi liquid. We show that precocity to pair condensation with doping is
a natural property of competing antiferromagnetism and d-wave superconductivity on a singly-occupied lattice, thus generalizing the Cooper instability to doped Mott insulators, with
significant implications for the high-temperature superconducting mechanism. |
