Luttinger liquid of trimers in Fermi gases with unequal masses | Giuliano Orso

9 Jul 2009 | Abstract: | We investigate one dimensional attractive Fermi gases in spin-dependent
optical lattices. Starting from the asymmetric Hubbard model, we show that
three-body bound states - ’’trimers’’ - exist as soon as the two tunneling
rates are different. We calculate the binding energy and the effective mass of
a single trimer. We then show numerically that for finite commensurate
densities $n_uparrow=n_downarrow/2$ an energy gap appears, implying that the
gas is a one-component Luttinger liquid of trimers with suppressed superfluid
ordering. The boundaries of this exotic phase are given. | Source: | arXiv, 0907.1533 | Services: | Forum | Review | PDF | Favorites |
