Properties of the non-linear Holstein polaron at finite doping and temperature
Shaozhi Li, E. A. Nowadnick, 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 add…

The effects of non-linear electron-phonon interactions on superconductivity and charge-density-wave correlations
Shaozhi Li, S. Johnston
Determinant quantum Monte Carlo (DQMC) simulations are used to study non-linear electron-phonon interactions in a two-dimensional Holstein-like model on a square lattice. We examin…
