文摘

We got the spin current operator using the Schwinger boson formalism. We employed the Kubo formula and we got the spin conductivity for this model. We found a sudden variation oft he height of peak in the range where the parameter Dc falls to zero in the graphic Dc vs. h. Therefore we obtain an influence of the quantum phase transition on the spin transport.
