Parallel Scan Recurrent Neural Quantum States for Scalable Variational Monte Carlo
Ejaaz Merali, Mohamed Hibat-Allah, Mohammad Kohandel +2
Neural-network quantum states have emerged as a powerful variational framework for quantum many-body systems, with recent progress often driven by massively parallel architectures…
Finite-Temperature Ferromagnetic Correlations of the Kagome Lattice Hubbard Model
Francisco Correia, Kyle Corbett, Ehsan Khatami
The Kagome lattice Fermi-Hubbard model is one of the most physically rich, and at the same time most challenging, models to study in strongly-correlated physics. Among its special…
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…
