Localization and mobility edges in the off-diagonal quasiperiodic model with slowly varying potentials
Tong Liu, Gao Xianlong, Shihua Chen +1
We study a one-dimensional system that includes both a commensurate off-diagonal modulation of the hopping amplitude and an incommensurate, slowly varying diagonal on-site modulati…
Component separation of two-component fermion clouds in a spin-dependent external potential by spin-density-functional theory
Gao Xianlong
We investigate the component separation in one-dimensional two-component fermion clouds in a spin-dependent external potential. The density distributions and the state diagram are…
The demixing of the two-component fermions in optical lattices under a spin-dependent external potential
A-Hai Chen, Gao Xianlong
The demixing of two-component fermions in optical lattices under a spin-dependent external potential is investigated using the density-matrix renormalization group method. The infl…
Absence of Wigner molecules in one-dimensional few-fermion systems with short-range interactions
Jing-Jing Wang, Wei Li, Shu Chen +3
We study by means of exact-diagonalization techniques the ground state of a few-fermion system with strong short-range repulsive interactions trapped by a harmonic potential in one…
Pure Fulde-Ferrell-Larkin-Ovchinnikov state in optical lattices
A-Hai Chen, Gao Xianlong
We study the phase diagram of a one-dimensional, two-component attractive fermions on optical lattices in an off-diagonal confinement. We identify in this system a pure Fulde-Ferre…
Effects of interaction and polarization on spin-charge separation: A time-dependent spin-density-functional theory study
Gao Xianlong
We calculate the nonequilibrium dynamic evolution of a one-dimensional system of two-component fermionic atoms after a strong local quench by using a time-dependent spin-density-fu…
Phase separation in optical lattices in a spin-dependent external potential
A-Hai Chen, Gao Xianlong
We investigate the phase separation in one-dimensional Fermi gases on optical lattices. The density distributions and the magnetization are calculated by means of density-matrix re…
Effect of disorder on the interacting Fermi gases in a one-dimensional optical lattice
Gao Xianlong, M. Polini, M. P. Tosi +1
Interacting two-component Fermi gases loaded in a one-dimensional (1D) lattice and subjected to an harmonic trapping potential exhibit interesting compound phases in which fluid re…
Time-dependent current-density-functional theory of spin-charge separation and spin drag in one-dimensional ultracold Fermi gases
Gao Xianlong, Marco Polini, Diego Rainis +2
Motivated by the large interest in the non-equilibrium dynamics of low-dimensional quantum many-body systems, we present a fully-microscopic theoretical and numerical study of the…
Effects of disorder on atomic density waves and spin-singlet dimers in one-dimensional optical lattices
Gao Xianlong
Using the Bethe-ansatz density-functional theory, we study a one-dimensional Hubbard model of confined attractively interacting fermions in the presence of a uniformly distributed…
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…

Gao Xianlong, Marco Polini, Mario P. Tosi +2
We present a novel and comprehensive microscopic study of Luther-Emery-paired phases in a strongly interacting atomic Fermi gas inside a parabolic trap and a one-dimensional (1D) o…

Gao Xianlong, W. Wonneberger
A many body theory for a two-component system of spin polarized interacting fermions in a one-dimensional harmonic trap is developed. The model considers two different states of th…
