Realization of adiabatic population transfer in a three-level system by using LR Hermitian invariants theory

摘要: We have studied the population transfer in a three-state system driven by laser beams terms of theory Lewis-Riesenfeld Hermitian invariants for explicitly time-dependent Hamiltonian. The exact solutions obtained allow us to recover two existing schemes producing complete literature, i.e. π-pulse and stimulated Raman adiabatic passage methods our unified description. present strict formulation conditions more accurate expression method according time-evolution state vector.
