Density-functional theory of inhomogeneous electron systems in thin quantum wires
S. H. Abedinpour, M. Polini, Gao Xianlong +1
Motivated by current interest in strongly correlated quasi-one-dimensional (1D) Luttinger liquids subject to axial confinement, we present a novel density-functional study of few-e…
Emergence of Wigner molecules in one-dimensional systems of repulsive fermions under harmonic confinement
S. H. Abedinpour, M. Polini, Gao Xianlong +1
A Bethe-Ansatz spin-density functional approach is developed to evaluate the ground-state density profile in a system of repulsively interacting spin-1/2 fermions inside a quasi-on…
Luther-Emery Phase and Atomic-Density Waves in a Trapped Fermion Gas
Gao Xianlong, M. Rizzi, Marco Polini +4
The Luther-Emery liquid is a state of matter that is predicted to occur in one-dimensional systems of interacting fermions and is characterized by a gapless charge spectrum and a g…
Interacting Fermi Gases in Disordered One-Dimensional Lattices
Gao Xianlong, M. Polini, B. Tanatar +1
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 wi…
