Our approach builds on the work presented in Refs. [1] and [17]. It also extends the recent work [52], which explored coherently controlled adiabatic passage in molecular dissociation. In the present study we describe the influence of temperature on the PA process and demonstrate how ARPA can be used to read the information encoded in the incoming wavefunction. Based on the calculations of Ref. [17], we discuss the role of incoherent initial conditions. 

P3/2), and 3)= D3/2,5/2). However, the imidirectional incoherent pumping is a stringent requirement. This perhaps may be achieved by using ultrafast pulses or coherently controlled adiabatic passage [116,117].

Coherent excitation of quantum systems by external fields is a versatile and powerful tool for application in quantum control. In particular, adiabatic evolution has been widely used to produce population transfer between discrete quantum states. Eor two states the control is by means of a varying detuning (a chirp), while for three states the change is induced, for example, by a pair of pulses, offset in time, that implement stimulated Raman adiabatic passage (STIRAP) [1-3]. STIRAP produces complete population transfer between the two end states 11) and 3) of a chain linked by two fields. In the adiabatic limit, the process places no temporary population in the middle state 2), even though the two driving fields - pump and Stokes-may be on exact resonance with their respective transitions, 1) 2)and... 

V. Engel Prof. Neusser, you mentioned the technique of Stimulated Raman Rapid Adiabatic Passage STIRAP, which allows for the coherent transfer of vibrational population selectively. Is the technique not another very efficient and experimentally verified scheme of coherent control ...
