Manifestations of the electron-phonon interaction range in angle-resolved photoemission spectra
Manifestations of the electron-phonon interaction range in angle-resolved photoemission spectra
Numerous angle resolved photoemission spectroscopy (ARPES) studies of a wide class of low-density metallic systems, ranging from doped transition metal oxides to quasi two-dimensional interfaces between insulators, exhibit phonon sidebands below the quasi-particle peak as a unique hallmark of polaronic correlations. Here, we single out properties of ARPES spectra that …
