Abstract

We study the spin-polaron interaction in the presence of simple scattering centers via Kubo formulation. The correlation function associated with the dc conductivity is obtained using the Matsubara Green’s function method. The first contributing term in the perturbation expansion is from the impurity interaction of the charge carriers. In the n = 2 perturbation expansion of the correlation, the spin-polaron interaction and the hole-impurity interaction can be treated separately.
