Nonadiabatic transition curve-crossing type

In the above numerical examples the held parameter F is taken to be the laser frequency and the nonadiabatic transition used is the Landau-Zener type of curve-crossing. The periodic chirping method, however, can actually be more... 

Nonadiabatic transitions play crucial roles in various fields of physics and chemistry [1. 2. 3. 4. 5, 7, 8 9. 10], and it is quite important to develop basic analytical theories so that we can understand fundamental mechanisms of various dynamics. The most fundamental models among them are the Landau-Zener type curve crossing and the Rosen-Zener-Demkov type non-curve-crossing. Furthermore, there is an interesting intermediate case in which two diabatie exponential potentials arc... 

Another kind of radially induced nonadiabatic transition is the Rosen-Zener-Demkov type (1,2). In contrast to the curve-crossing case, the two diabatic potentials have very weak / -dependence (actually, their difference is assumed to be constant in the basic model) and the diabatic coupling has a strong (-exponential) / -dependence (see Fig. 5). The nonadiabatic transition is not as effective as the curve-crossing case, but this case also presents an important transition, especially when the two potentials are near resonance asymptotically.
