Landau-Zener问题的Wei-Norman-Kolokolov方法
Wei-Norman-Kolokolov approach for Landau-Zener problems
摘要:
利用$SU(2)$李群指数序Wei-Norman方法研究了任意自旋$S$的$2S+1$塞曼多重态之间的隧穿.考虑了自旋在规则含时磁场和横向色噪声作用下的运动,研究了快噪声和慢噪声的区域。
英文摘要:
The tunneling between the $2S+1$ Zeeman multiplets of an arbitrary spin $S$ using the $SU(2)$ Lie group exponential ordering Wei-Norman technique is investigated. A spin subjected to a regular time-dependent magnetic field and a transverse colored noise is considered and the regimes of fast and slow noise examined.
