We investigate the ground-state properties of trapped fermion systems described by the
Hubbard model with an external confining potential. We discuss the universal behaviors of …

The dynamic structure factors reflecting the excitation spectra were investigated in a one-
dimensional (1D) optical lattice with a spin-orbit coupling (SOC) effect. The results reveal …

Strongly interacting atoms trapped in optical lattices can be used to explore phase diagrams
of Hubbard models. Spatial inhomogeneity due to trapping typically obscures distinguishing …

A system of a finite number of harmonically trapped fermions in one dimension, in the
presence of a static magnetic field, is studied within the framework of the static fluctuation …

We show that, for fermionic atoms in a one-dimensional optical lattice, the fraction of atoms
in doubly occupied sites is a highly nonmonotonic function of temperature. We demonstrate …

本文通过数值求解有限温度下一维均匀费米Gaudin-Yang 模型的热力学Bethe-ansatz 方程,

We study long-time spin diffusion of harmonically trapped lattice fermions in one dimension.
Combining thermodynamic Bethe ansatz approach and local-density approximation, we …

By investigating the compressibility of one-dimensional lattice fermions at various filling
factors, we study the phase separation and re-entrant transition within the framework of the …
