Title: Isotope effect on the electron band structure of doped insulators
Authors: Kornilovitch, P.E.
Alexandrov, A.S.
Keywords: Superconductivity
Strongly correlated electrons
Issue Date: 2004
Abstract: Applying a continuous-time quantum Monte-Carlo algorithm we calculate the exact coherent band dispersion and the density of states of a two dimensional lattice polaron in the region of parameters where any approximation might fail. We find an isotope effect on the band structure, which is different for different wave-vectors of the Brillouin zone and depends on the radius and strength of the electron-phonon interaction. An isotope effect on the electron spectral function is also discussed.
