We report on a numerical study of the double layer Hubbard model describing the CuO 2 sheets in the high- $T_{\rm c}$ 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 ...

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.
