Effects of electron-phonon coupling in the Kondo regime of a two-orbital molecule
Effects of electron-phonon coupling in the Kondo regime of a two-orbital molecule
We study the interplay between strong electron-electron and electron-phonon interactions within a two-orbital molecule coupled to metallic leads, taking into account Holstein-like coupling of a local phonon mode to the molecular charge as well as phonon-mediated interorbital tunneling. By combining canonical transformations with numerical renormalization-group calculations to address the interactions …
