Finite-momentum pairing and magnetic halos in a spin-imbalanced Holstein model
Chunhan Feng, George Batrouni, Richard Scalettar
Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductivity, Cooper pairing at finite-momentum driven by spin imbalance, remains difficult to study numerically in two dimensions. The…
The SU(N) Holstein Model
Chunhan Feng, Linh Pham, George Batrouni +1
From the condensed matter physics perspective, the most natural single orbital tight-binding Hamiltonians, and hence the most widely studied, contain two fermionic species, corresp…
Fast and scalable quantum Monte Carlo simulations of electron-phonon models
Benjamin Cohen-Stead, Owen Bradley, Cole Miles +3
We introduce methodologies for highly scalable quantum Monte Carlo simulations of electron-phonon models, and report benchmark results for the Holstein model on the square lattice.…
Competition between Phase Separation and Spin Density Wave or Charge Density Wave Order: Role of Long-Range Interactions
Bo Xiao, F. Hébert, G. Batrouni +1
Recent studies of pairing and charge order in materials such as FeSe, SrTiO, and 2H-NbSe have suggested that momentum dependence of the electron-phonon coupling plays an im…
Symmetry Enforced Self-Learning Monte Carlo Method Applied to the Holstein Model
Chuang Chen, Xiao Yan Xu, Junwei Liu +3
Self-learning Monte Carlo method (SLMC), using a trained effective model to guide Monte Carlo sampling processes, is a powerful general-purpose numerical method recently introduced…
Impurities near an Antiferromagnetic-Singlet Quantum Critical Point
T. Mendes, N. Costa, G. Batrouni +4
Heavy fermion systems, and other strongly correlated electron materials, often exhibit a competition between antiferromagnetic (AF) and singlet ground states. Using exact Quantum M…
