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…
Phase diagram of the two-dimensional Hubbard-Holstein model: enhancement of -wave pairing between charge and magnetic orders
Natanael C. Costa, Kazuhiro Seki, Seiji Yunoki +1
We investigate the role of electron-electron and electron-phonon interactions in strongly correlated systems by performing unbiased quantum Monte Carlo simulations in the square la…
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…
Effect of Strain on Charge Density Wave Order in the Holstein Model
B. Cohen-Stead, N. C. Costa, E. Khatami +1
We investigate charge ordering in the Holstein model in the presence of anisotropic hopping, , as a model of the effect of strain on charge density wave (CDW)…
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…
