Charge Order in the half-filled bond-Holstein Model
Charles Jordan, George Issa, Ehsan Khatami +3
We use determinant quantum Monte Carlo to study the half-filled `bond-Holstein' model on a square lattice. We find that the model exhibits a charge-density-wave (CDW) phase transit…
Antiferromagnetic and bond-order-wave phases in the half-filled two-dimensional optical Su-Schrieffer-Heeger-Hubbard model
Andy Tanjaroon Ly, Benjamin Cohen-Stead, Steven Johnston
Electron-phonon (-ph) interactions arise in many strongly correlated quantum materials from the modulation of the nearest-neighbor hopping integrals, as in the celebrated Su-Sch…
Optimizing the Critical Temperature and Superfluid Density of a Metal-Superconductor Bilayer
Yutan Zhang, Philip M. Dee, Benjamin Cohen-Stead +3
A promising path to realizing higher superconducting transition temperatures is the strategic engineering of artificial heterostructures. For example, quantum materials could…
