Wei-Norman-Kolokolov approach for Landau-Zener problems

Abstract

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.
