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…
Renormalization of spectra by phase competition in the half-filled Hubbard-Holstein model
E. A. Nowadnick, S. Johnston, B. Moritz +1
We present electron and phonon spectral functions calculated from determinant quantum Monte Carlo simulations of the half-filled two-dimensional Hubbard-Holstein model on a square…
Persistent spin excitations in doped antiferromagnets revealed by resonant inelastic light scattering
C. J. Jia, E. A. Nowadnick, K. Wohlfeld +6
How coherent quasiparticles emerge by doping quantum antiferromagnets is a key question in correlated electron systems, whose resolution is needed to elucidate the phase diagram of…
Determinant quantum Monte Carlo study of the two-dimensional single-band Hubbard-Holstein model
S. Johnston, E. A. Nowadnick, Y. F. Kung +3
We have performed numerical studies of the Hubbard-Holstein model in two dimensions using determinant quantum Monte Carlo (DQMC). Here we present details of the method, emphasizing…
Competition between antiferromagnetic and charge density wave order in the half filled Hubbard-Holstein model
E. A. Nowadnick, S. Johnston, B. Moritz +2
We present a determinant quantum Monte Carlo study of the competition between instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between electrons, as…
