Abstract

We discuss the properties of quasi-one-dimensional quantum gases of fermionic atoms using the Luttinger liquid theory, including the presence of an optical lattice and of a longitudinal trapping potential. We analyse in particular the nature and manifestations of spin–charge separation, where in the case of atoms 'spin' and 'charge' refers to two internal atomic states and the atomic mass density, respectively.
