Vv. Flambaum et al., HOLE-HOLE SUPERCONDUCTING PAIRING IN THE T-J MODEL INDUCED BY LONG-RANGE SPIN-WAVE EXCHANGE, Physica. C, Superconductivity, 235, 1994, pp. 2217-2218
We demonstrate that long-range (r similar to p(F)(-1) >> lattice spaci
ng) spin-wave exchange produces a very strong pairing of the holes. So
lutions of the BCS-type equation for the superconducting gap Delta are
found for various symmetries. The strongest pairing corresponds to d-
wave symmetry.
