While phonons are generally considered to be irrelevant to the mechanism of high-temperature superconductivity, a large number of experimental results indicate otherwise. We argue that the electron-phonon coupling in strongly correlated electron systems is unconventional, and results in a strong spi
Using a simple, isotropic phonon model, the contribution of optic modes to the electron-phonon coupling constant is found to exceed that of acoustic phonons only slightly. The Coulomb pseudopotential parameter tz \* is found to be rather small. The inverse isotope effect is analyzed and related to c
