Abstract
This work analyzes theoretically the transport of spin in a one-dimensional quantum wire and compare it with recent experimental results with cold atoms. The spin conductance is shown to have a nonmonotonic temperature dependence, with spin perfectly conducted in the zero-temperature limit even in the spin-gapped phase.
