A recent experiment by Ma and collaborators shows that the gap anisotropy in Bi2Sr2Ca1Cu2O8+x is strongly temperature dependent. In particular, the superconducting gap along the Γ−M direction shows a weaker temperature dependence than the gap along the Γ−X direction which decreases rapidly with temperature. We explain this novel feature as a natural consequence of the interlayer tunneling mechanism of superconductivity.
