论文摘要
我们研究了大型$ s $限制中pyrochlore Heisenberg Antiferromagnet托管的经典自旋液体的能量和自旋运输。分子动力学计算表明,随着温度趋于零,能量和自旋扩散常数接近有限限。我们根据有效的疾病模型来解释我们的结果,其中能量/自旋携带正常模式在准静态无序的自旋背景中传播。然后,由于有效障碍,正常模式的有限平均自由路径的结果,自然理解了扩散常数的有限零温度极限。
We study the energy and spin transport of the classical spin liquid hosted by the pyrochlore Heisenberg antiferromagnet in the large $S$ limit. Molecular dynamics calculation suggests that both the energy and spin diffusion constants approach finite limits as the temperature tends to zero. We explain our results in terms of an effective disorder model, where the energy/spin-carrying normal modes propagate in a quasi-static disordered spin background. The finite zero temperature limits of the diffusion constants are then naturally understood as a result of the finite mean free path of the normal modes due to the effective disorder.
