Effects of Temperature and Magnetization on the Mott-Anderson Physics in one-dimensional Disordered Systems
G. A. Canella, K. Zawadzki, V. V. França
We investigate the Mott-Anderson physics in interacting disordered one-dimensional chains through the average single-site entanglement quantified by the linear entropy, which is ob…
Mott-Anderson Metal-Insulator Transitions from Entanglement
G. A. Canella, V. V. França
A metal can be driven to an insulating phase through distinct mechanisms. A possible way is via the Coulomb interaction, which then defines the Mott metal-insulator transition (MIT…
Uniqueness of density-to-potential mapping for fermionic lattice systems
J. P. Coe, I. D'Amico, V. V. França
We demonstrate that, for a fermionic lattice system, the ground-state particle density uniquely determines the external potential except for the sites corresponding to nodes of the…
Simple parametrization for the ground-state energy of the infinite Hubbard chain incorporating Mott physics, spin-dependent phenomena and spatial inhomogeneity
Vivian V. França, Daniel Vieira, Klaus Capelle
Simple analytical parametrizations for the ground-state energy of the one-dimensional repulsive Hubbard model are developed. The charge-dependence of the energy is parametrized usi…
Effect of spatial inhomogeneity on the mapping between strongly interacting fermions and weakly interacting spins
Vivian V. França, Klaus Capelle
A combined analytical and numerical study is performed of the mapping between strongly interacting fermions and weakly interacting spins, in the framework of the Hubbard, t-J and H…
Feasibility of approximating spatial and local entanglement in long-range interacting systems using the extended Hubbard model
J. P. Coe, V. V. França, I. D'Amico
We investigate the extended Hubbard model as an approximation to the local and spatial entanglement of a one-dimensional chain of nanostructures where the particles interact via a…
The Hubbard model as an approximation to the entanglement in nanostructures
J. P. Coe, V. V. França, I. D'Amico
We investigate how well the one-dimensional Hubbard model describes the entanglement of particles trapped in a string of quantum wells. We calculate the average single-site entangl…
Entanglement in spatially inhomogeneous many-fermion systems
V. V. França, K. Capelle
We investigate entanglement of strongly interacting fermions in spatially inhomogeneous environments. To quantify entanglement in the presence of spatial inhomogeneity, we propose…
Entanglement entropy and entanglement witnesses in models of strongly interacting low-dimensional fermions
V. V. França, K. Capelle
We calculate the entanglement entropy of strongly correlated low-dimensional fermions in metallic, superfluid and antiferromagnetic insulating phases. The entanglement entropy refl…
