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…
Finite-Temperature Quantum Matter with Rydberg or Molecule Synthetic Dimensions
Sohail Dasgupta, Chunhan Feng, Bryce Gadway +2
Synthetic dimension platforms offer unique pathways for engineering quantum matter. We compute the phase diagram of a many-body system of ultracold atoms (or polar molecules) with…
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…
Metal-insulator transition and magnetism of SU(3) fermions in the square lattice
Eduardo Ibarra-García-Padilla, Chunhan Feng, Giulio Pasqualetti +4
We study the SU(3) symmetric Fermi-Hubbard model (FHM) in the square lattice at -filling using numerically exact determinant quantum Monte Carlo (DQMC) and numerical linked-cl…
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…
