Density of eigenvalues and its perturbation invariance in unitary ensembles of random matrices
Dang-Zheng Liu, Zheng-Dong Wang, Kui-Hua Yan
We generally study the density of eigenvalues in unitary ensembles of random matrices from the recurrence coefficients with regularly varying conditions for the orthogonal polynomi…
Controlling soliton interactions in Bose-Einstein condensates by synchronizing the Feshbach resonance and harmonic trap
Xiao-Fei Zhang, Qin Yang, Jie-Fang Zhang +2
We present how to control interactions between solitons, either bright or dark, in Bose-Einstein condensates by synchronizing Feshbach resonance and harmonic trap. Our results show…
Collective excitations in one-dimensional ultracold Fermi gases: a comparative study
Wei Li, Gao Xianlong, Corinna Kollath +1
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 simp…
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…
Spin density-functional theory for imbalanced interacting Fermi gases in highly elongated harmonic traps
Gao Xianlong, Reza Asgari
We numerically study imbalanced two component Fermi gases with attractive interactions in highly elongated harmonic traps. An accurate parametrization formula for the ground state…
