Description:
Author(s): Shaozhi Li, E. A. Nowadnick, and S. Johnston We use determinant quantum Monte Carlo to study the single-particle properties of quasiparticles and phonons in a variant of the two-dimensional Holstein model that includes an additional nonlinear electron-phonon (e-ph) interaction. We find that a small positive nonlinear interaction reduces the ef… [Phys. Rev. B 92, 064301] Published Mon Aug 03, 2015
