摘要： The population transfer in effective three-state systems driven by laser beams has been studied based on the theory of Lewis－Riesenfeld Hermitian invariants in the full- and partial-adiabatic approximations. A strict formulation of adiabatic conditions is given, and a new adiabatic condition for inducing a complete population transfer is found.

关键词: adiabatic population transfer, Lewis－Riesenfeld Hermitian invariant, π-pulse method, stimulated Raman adiabatic passage methods

A strict formulation of adiabatic conditions is given, and a new adiabatic condition for inducing a complete population transfer is found.
