摘要：

We present results for the spin conductance of the one-dimensional spin-1/2 Heisenberg and XY models coupled to phonons. We apply an approach based on the stochastic series expansion (quantum Monte Carlo) method to evaluate the conductance for a variety of phonon dispersions and values of spin-phonon coupling. From our numerical simulations and analytical arguments, we derive several scaling laws for the conductance.
