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…

Learning by Confusion: The Phase Diagram of the Holstein Model
George Issa, Owen Bradley, Ehsan Khatami +1
We employ the "learning by confusion" technique, an unsupervised machine learning approach for detecting phase transitions, to analyze quantum Monte Carlo simulations of the two-di…
