Electron-phonon coupling in a two-dimensional inhomogeneous electron gas : consequences for surface spectral properties

摘要: We investigate the coupling of an inhomogeneous electron system to phonons. The properties electronic composed a mixture microscopic ordered and disordered islands are changed fundamentally by phonon mode. In high-Tc cuprates, such phase separation scenario is supported recent STM nuclear quadrupole resonance studies. show that even weak or moderate electron–phonon can be sufficient produce dramatic changes in state gas. spectral calculated our approach provide natural explanation low-energy nodal ARPES features exhibit novel non-Fermi-liquid stabilized through coupling.
