Dissipation and decoherence in collision processes: Beyond dynamical symmetry and the non-autonomous quantum master equation

摘要: Abstract Based on the non-autonomous quantum master equation which describes collision between a two-level system and other atoms or molecules, we investigate systemic dissipative decoherence properties. Using novel algebraic dynamic method, found SU ( 2 ) ⊕ U 1 dynamical symmetry of this obtained exact solutions. Furthermore, asymptotic behaviors have been investigated.
