自旋冰中的热猝灭
Thermal quenches in spin ice
摘要：
我们研究的扩散湮灭过程中发生的自旋冰淬火时，从高温顺磁相深入到自旋冰制度，其中的激发-磁单极-是稀疏的。我们发现，由于库仑之间的相互作用的单极子，动态逮捕发生，其中“非普遍的”晶格尺度的限制阻碍了完全衰减的电荷波动。这一现象超出了双组分库仑液体的通用平均场论的范围。我们确定了相关的时间尺度的动态逮捕，并提出了一个实验，用于检测磁单极子和他们的动态自旋冰的基础上，这种非平衡现象。
英文摘要：
We study the diffusion annihilation process which occurs when spin ice is quenched from a high temperature paramagnetic phase deep into the spin ice regime, where the excitations -- magnetic monopoles -- are sparse. We find that due to the Coulomb interaction between the monopoles, a dynamical arrest occurs, in which `non-universal' lattice-scale constraints impede the complete decay of charge fluctuations. This phenomenon is outside the reach of universal mean-field theory for a two-component Coulomb liquid. We identify the relevant timescales for the dynamical arrest and propose an experiment for detecting monopoles and their dynamics in spin ice based on this non-equilibrium phenomenon.
