Kondo-attractive-Hubbard model for the ordering of local magnetic moments in superconductors
(Amer Physical Soc, 2009-06-01)
We consider local magnetic moments coupled to conduction electrons with on-site attraction in order to discuss the interplay between pairing and magnetic order. We probe the ground-state properties of this model on a ...

Competition between spin, charge, and bond waves in a Peierls-Hubbard model
(1996-12-01)
We study a one-dimensional extended Peierls-Hubbard model coupled to intracell and intercell phonons for a half-filled band. The calculations are made using the Hartree-Fock and adiabatic approximations for arbitrary ...

Density wave propagation in a two-dimensional random dimer potential: From a single to a bipartite square lattice
(American Physical Society, 2020-01)
We study the propagation of a density perturbation in a weakly interacting boson gas confined on a lattice and in the presence of square dimerized impurities. Such a two-dimensional dual random dimer model (2D DRDM), ...
Charge dynamics in half-filled Hubbard chains with finite on-site interaction
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
We study the charge dynamic structure factor of the one-dimensional Hubbard model with finite on-site repulsion U at half-filling. Numerical results from the time-dependent density matrix renormalization group are analyzed ...
