Dynamical resilience to disorder: the dilute Hubbard model on the Lieb lattice
L. Oliveira-Lima, N. C. Costa, J. Pimentel de Lima +2
In itinerant systems, electron-electron interactions may lead to the formation of local magnetic moments and their effective exchange coupling, which in turn gives rise to long-ran…
Charge Density Waves on a Half-Filled Decorated Honeycomb Lattice
Chunhan Feng, Huaiming Guo, Richard T. Scalettar
Tight binding models like the Hubbard Hamiltonian are most often explored in the context of uniform intersite hopping . The electron-electron interactions, if sufficiently large…
Charge Density Wave and Superconductivity in the Disordered Holstein Model
Bo Xiao, Natanael C. Costa, Ehsan Khatami +2
The interplay between electron-electron correlations and disorder has been a central theme of condensed matter physics over the last several decades, with particular interest in th…
Self-Organized Bosonic Domain Walls
Xingchuan Zhu, Shiying Dong, Yang Lin +4
Hardcore bosons on honeycomb lattice ribbons with zigzag edges are studied using exact numerical simulations. We map out the phase diagrams of ribbons with different widths, which…
Determinant Quantum Monte Carlo Study of Exhaustion in the Periodic Anderson Model
Lufeng Zhang, Tianxing Ma, Natanael C. Costa +2
The Kondo and Periodic Anderson models describe many of the qualitative features of local moments coupled to a conduction band, and thereby the physics of materials such as the hea…
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…
