Abstract

Spin is a particle property whose study of transport receives attention due to lossless transfer of information. In this study, spin transport is dependent on interparticle interactions in a one-dimensional half-filled open elastic Fermi-Hubbard optical lattice. Near absolute zero temperature temperature, spins flow in the repulsive regime and are not transported in the attractive regime. In addition, as the temperature approaches zero, the abrupt increase of the conductivity for the repulsive regime and the decrease to zero of the conductivity for the attractive regime take place at relatively higher temperatures.
