Abstract

The mechanism involving phonons and lochons (local charged bosons, local pairs) developed earlier for cuprate superconductors is applied for the study of the gap anisotropy in these systems. It is found that besides intraplanar pairing the lochon-induced interlayer pairing gives rise to an anisotropic s-wave gap which is capable of changing sign in some regions on the Fermi surface.
