摘要：

Exact diagonalizations of two-dimensional t-J dusters reveal dominant hole-hole correlations at distance root 2 (i.e., between holes on next-nearest-neighbor sites). A singlet d(x2-y2) pair operator is proposed to account for the spatial extension of the two-hole-bound pair beyond nearest-neighbor sites.
