In this theory, an attractive potential exists within a Debye energy of the Fermi surface and this theory's successes include the explanation of the isotope effect and the prediction of the energy gap in the excitation spectrum after transition.
The effective potential in this theory includes a term known as the "vector correction", which is logarithmic in in the ratio of the frequency to the Debye frequency. This theory uses three Green's correlation functions whose poles give the excitation energy, and much of the experimental corroboration for this theory came from electron tunneling experiments conducted by Ivar Giaever. In this theory, an attractive potential exists within a Debye energy of the Fermi surface and this theory's successes include the explanation of the isotope effect and the prediction of the energy gap in the excitation spectrum after transition. For 10 points, identify this theory in which the interaction of phonons with electron pairs results in superconductivity, named for its three formulators.
