Abstract

We present results obtained (by exact diagonalization) for the problem of two t-J planes with an interlayer coupling t⊥. Our results for small hole concentrations show that in-plane superconducting correlations are enhanced by t⊥. When the constraint on double occupancy in the t-J model is relaxed, the enhancement disappears. These results illustrate the interlayer tunneling mechanism for superconductivity.
