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…
Magnetic, charge, and bond order in the two-dimensional Su-Schrieffer-Heeger-Holstein model
Max Casebolt, Chunhan Feng, Richard T. Scalettar +2
Most nonperturbative numerical studies of electron-phonon interactions focus on model Hamiltonians where the electrons interact with a phonon branch via a single type of microscopi…
Attractive Su-Schrieffer-Heeger-Hubbard Model on a Square Lattice Away from Half-Filling
Bo Xing, Chunhan Feng, Richard Scalettar +2
The Su-Schrieffer-Heeger (SSH) model, with bond phonons modulating electron tunneling, is a paradigmatic electron-phonon model that hosts an antiferromagnetic order to bond order t…
Metal-insulator transition and quantum magnetism in the SU(3) Fermi-Hubbard Model: Disentangling Nesting and the Mott Transition
Chunhan Feng, Eduardo Ibarra-García-Padilla, Kaden R. A. Hazzard +3
We use state-of-the-art numerical techniques to compute ground state correlations in the two-dimensional SU(3) Fermi Hubbard model at -filling, modeling fermions with three po…
Enhancement of Charge Density Wave Correlations in a Holstein Model with an Anharmonic Phonon Potential
C. Kvande, C. Feng, F. Hébert +2
The Holstein Hamiltonian describes itinerant electrons whose site density couples to local phonon degrees of freedom. In the single site limit, at half-filling, the electron-phonon…
Bose-Einstein condensation in honeycomb dimer magnets and
Chunhan Feng, E. Miles Stoudenmire, Alexander Wietek
An asymmetric Bose-Einstein condensation (BEC) dome was observed in a recent experiment on the quantum dimer magnet , which is modeled by a "breathing" honeycomb l…
