Description

The angle-resolved photoemission spectrum is derived for systems with strong electron-phonon coupling. Polaronic features of the charge carriers are manifest in a broad spectrum, with a maximum at an energy (below the Fermi energy) corresponding to the polaron binding energy. In the strong-coupling limit and with dispersionless phonons an oscillatory structure is superposed on this broad spectrum with a frequency equal to the characteristic phonon frequency
