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…
Density-Functional Theory of Graphene Sheets
Marco Polini, Andrea Tomadin, Reza Asgari +1
We outline a Kohn-Sham-Dirac density-functional-theory (DFT) scheme for graphene sheets that treats slowly-varying inhomogeneous external potentials and electron-electron interacti…
Spin-drag relaxation time in one-dimensional spin-polarized Fermi gases
Diego Rainis, Marco Polini, M. P. Tosi +1
Spin propagation in systems of one-dimensional interacting fermions at finite temperature is intrinsically diffusive. The spreading rate of a spin packet is controlled by a transpo…
The low-energy excitation spectrum of one-dimensional dipolar quantum gases
S. De Palo, E. Orignac, R. Citro +1
We determine the excitation spectrum of a bosonic dipolar quantum gas in a one-dimensional geometry, from the dynamical density-density correlation functions simulated by means of…
Fulde-Ferrell-Larkin-Ovchinnikov superfluidity in one-dimensional optical lattices
M. Rizzi, Marco Polini, M. A. Cazalilla +3
Spin-polarized attractive Fermi gases in one-dimensional (1D) optical lattices are expected to be remarkably good candidates for the observation of the Fulde-Ferrell-Larkin-Ovchinn…
