Model of the electron-phonon interaction and optical conductivity of Ba(1-x)K(x)BiO(3) superconductors.

Abstract

We investigate the physical properties of the Ba(1-x)K(x)BiO(3) compounds with a focus on the optical properties. Results from the simple Holstein model, describing a single band coupled to an oxygen breathing mode with parameters derived from first principles calculations, are in excellent agreement with a broad range of experimental information. It… (More)
