Abstract
We report on a numerical study of the double layer Hubbard model describing the CuO
2 sheets in the high-
oxides. For the simulation we employed the projector quantum Monte Carlo method (PQMC) to study the ground state properties
of this correlated electron system. Our results provide evidence for off-diagonal long range order in the nodeless d-wave
channel. The implications with respect to possible mechanisms for high-
superconductivity in oxides in combination which phononic booster mechanisms are discussed.
