Large size two-hole bound states in t-J model

Condensed Matter 2009-10-22 v1

Abstract

Several series of shallow large-size (llattice spacingl \gg lattice~ spacing) two-hole bound states are found in the two-dimensional t-J model. Their binding energies depend exponentially on the inverse value of the hole-spin-wave coupling constant. Their parity is connected with the angular wave function in a nonstandard way. The possible role of these states in the formation of superconducting pairing is considered.
