Adiabatic following for a three-state quantum system

Adiabatic time-evolution – found in various forms of adiabatic following and adiabatic passage – is often advantageous for controlled manipulation of quantum systems due to its insensitivity to deviations in the pulse shapes and timings. In this paper we discuss controlled adiabatic evolution of a t...

Summary:Adiabatic time-evolution – found in various forms of adiabatic following and adiabatic passage – is often advantageous for controlled manipulation of quantum systems due to its insensitivity to deviations in the pulse shapes and timings. In this paper we discuss controlled adiabatic evolution of a three-state quantum system, a natural advance to the widespread use of two-state systems in numerous contemporary applications. We discuss, and illustrate, not only possibilities for population transfer but also for creating, with prescribed relative phase, 50:50 superpositions of two Zeeman sublevels in a letter-vee coupling linkage. •We presented adiabatic following in a three-state system subject to a single driving detuned driving field.•We showed that depending on the initial state, several final states can be prepared in a robust fashion.•The model treated in the manuscript may have application to the behavior of three coupled planar-waveguides and frequency conversion.
