摘要:

利用Liouville-vonNeumann方程的解复化,得到了三个磁量子在任意的、含时的、外磁场中的局域Bloch矢量和自旋关联函数的封闭方程组.给出了动力学方程的推导算法。在便于重要物理应用的基础上,计算了代数su(2S+1)的结构常数.

英文摘要:

A closed system of equations for the local Bloch vectors and spin correlation functions of three magnetic qudits, which are in an arbitrary, time-dependent, external magnetic field, is obtained using decomplexification of the Liouville-von Neumann equation. The algorithm of the derivation of the dynamic equations is presented. In the basis convenient for the important physical applications structure constants of algebra su(2S+1) are calculated.
