Fulde-Ferrell-Larkin-Ovchinnikov pairing in one-dimensional optical lattices
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-Ovchinnikov (FFLO) phase. We model these systems with an attractive Hubbard model with population imbalance. By means of the density-matrix renormalization-group method, we compute the pairing correlations as well as the static spin and charge structure factors in the whole range from weak to strong coupling. We demonstrate that pairing correlations exhibit quasi-long-range order and oscillations at the wave number expected from the FFLO theory. However, we also show by numerically computing the mixed spin-charge static …
Liquid Dichlorides and Dichloride-Monochloride Mixtures
We give a short review of the progress done recently in the interpretation of the structure of molten divalent cation chlorides and of the stability of chloro complexes in molten salt mixtures.
