Nonadiabatic breakdown and pairing in high-Tc compounds
The electron-phonon interaction plays a fundamental role on the superconducting and normal
 state properties of all the high-Tc materials, from cuprates to fullerenes. Another common element
 of these compounds is in addition the extremely small Fermi energy EF, which is comparable w...

| description | The electron-phonon interaction plays a fundamental role on the superconducting and normal
state properties of all the high-Tc materials, from cuprates to fullerenes. Another common element
of these compounds is in addition the extremely small Fermi energy EF, which is comparable with
the range ωph of the phonon frequencies. In the situation the adiabatic principle ωph/EF 1, on
which the standard theory of the electron-phonon interaction and of the superconductivity relies,
breaks down. In this contribution we discuss the physical consequences of the breakdown of the
adiabatic assumption, with special interest on the superconducting properties. We review the microscopic
derivation of the nonadiabatic theory of the electron-phonon coupling which explicitly
takes into account higher order electron-phonon scattering not included in the conventional picture.
Within this context we discuss also the role of the repulsive electron-electron correlation and
the specific phenomenology of cuprates and fullerides.
