Spin diffusion in the one-dimensional classical Heisenberg model
Spin diffusion in the one-dimensional classical Heisenberg model
The problem of spin diffusion is studied numerically in one-dimensional classical Heisenberg model using a deterministic odd even spin precession dynamics. We demonstrate that spin diffusion in this model, like energy diffusion, is normal and one obtains a long time diffusive tail in the decay of autocorrelation function (ACF). Some …
