| Description/Abstract | The coupled Eliashberg-like integral equations for the self-energy and the pairing amplitude of two holes in real space are derived within the {ital t}-{ital J} model.^From the calculation of the Eliashberg spectral density function {alpha}{sup 2}{ital F}({omega}), the configurations of two holes in real space can be determined.^It is found that two holes on adjacent sites have the strongest attractive interaction, but the pairing amplitude vanishes.^This indicates that the holes cannot form local pairs within the {ital t}-{ital J} model regardless of whether the effective interaction between the holes is attractive.^The spectral function of the holes is calculated.^At the strong-coupling limit, the similarity between our result for a single hole and that of the retraceable-path approximation of Brinkman and Rice is also discussed. |
