Density-functional theory approach to the thermodynamics of the harmonically confined one-dimensional Hubbard model
V. L. Campo
The thermodynamics of the inhomogeneous one-dimensional repulsive fermionic Hubbard model with parabolic confinement is studied by a density-functional theory approach, based on Me…
Thermal versus Quantum Fluctuations of Optical Lattice Fermions
V. L. Campo, K. Capelle, C. Hooley +2
We show that, for fermionic atoms in a one-dimensional optical lattice, the fraction of atoms in doubly occupied sites is a highly non-monotonic function of temperature. We demonst…
Extended DFT+U+V method with on-site and inter-site electronic interactions
Vivaldo Leiria Campo, Matteo Cococcioni
In this article we introduce a generalization of the popular DFT+U method based on the extended Hubbard model that includes on-site and inter-site electronic interactions. The nove…
Phase diagram of harmonically confined one-dimensional fermions with attractive and repulsive interactions
V. L. Campo, K. Capelle
We construct the complete - phase diagram for harmonically confined ultracold fermionic atoms with repulsive and attractive interactions. ( is the chemical potential and $…
