自旋-声子过程中的Angular momentum

Angular momentum in spin-phonon processes

D. A. Garanin, E. M. Chudnovsky

摘要:

弹性环境中自旋弛豫的量子理论根据Zhang和Niu(PRL 2014)最近引入的声子自旋的概念进行了修正。与电磁场的情况类似,将与弹性形变相关的角动量分为轨道部分和声子自旋部分,这对于分析角动量的平衡是有用的。这样的分析为解释爱因斯坦-德哈斯效应的微观过程提供了重要线索.

英文摘要:

Quantum theory of spin relaxation in the elastic environment is revised with account of the concept of a phonon spin recently introduced by Zhang and Niu (PRL 2014). Similar to the case of the electromagnetic field, the division of the angular momentum associated with elastic deformations into the orbital part and the part due to phonon spins proves to be useful for the analysis of the balance of the angular momentum. Such analysis sheds important light on microscopic processes leading to the Einstein - de Haas effect.
