Interacting two-component Fermi gases loaded in a one-dimensional (1D) lattice and subject to harmonic trapping exhibit intriguing compound phases in which fluid regions coexist with local Mott-insulator and/or band-insulator regions. Motivated by experiments on cold atoms inside disordered optical lattices, we present a theoretical study of the effects of a random potential on these ground-state phases. Within a density-functional scheme we show that disorder has two main effects: (i) it… Expand

Luther-Emery phase and atomic-density waves in a trapped fermion gas.
This Letter studies by means of the density-matrix renormalization-group technique a two-component atomic Fermi gas with attractive interactions subject to parabolic trapping inside an optical lattice and demonstrates how this system exhibits compound phases characterized by the coexistence of spin pairing and atomic-density waves.

Collective excitations in one-dimensional ultracold Fermi gases: Comparative study
Time-dependent density-functional theory (TDDFT) is a powerful tool to study the non-equilibrium dynamics of inhomogeneous interacting many-body systems. Here we show that the simple adiabaticExpand
The Hubbard dimer: a density functional case study of a many-body problem.
This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model, and explores the behavior of the gap and the many-body Green's function, demonstrating the 'failure' of the Kohn-Sham (KS) method to reproduce the fundamental gap.

Signature of Mott-insulator transition with ultracold fermions in a one-dimensional optical lattice.

Routes towards Anderson-like localization of Bose-Einstein condensates in disordered optical lattices.
Analysis of possible routes towards Anderson-like localization of Bose-Einstein condensates in disordered potentials shows that incommensurable superlattices should allow for the observation of the crossover from the nonlinear screening regime to the Anderson localized case within realistic experimental parameters.

Inhomogeneous metallic phase in a disordered Mott insulator in two dimensions.
The spectral gap in a 2D Mott-Hubbard insulator is destroyed first at a disorder V( c1), while antiferromagnetism persists up to a higher V(c2), resulting in a spatially inhomogeneous metallic phase. Expand
