Dynamical pairing correlations in the t-J model with non-adiabatic hole-phonon coupling
G. Wellein, B. B"auml, H. Fehske
Abstract
We examine the effects of hole-phonon interaction on the formation of hole pairs in the 2D Holstein t--J model. Using finite-lattice diagonalization techniques, we present exact results for the two-hole binding energy and the s-- and d-wave pairing susceptibilities.
