N2 - The analysis of problems related to nonlocalized population transfer between quantum levelsrequires nontraditional mathematical approaches. Here we study the processes of irremovable nonadiabatictransitions in a (N − 1)-dimensional system of completely degenerate so-called dark states, taking as a basemodel multilevel N-pod systems. It is shown that quantum dynamics of the dark states due to the operatorof nonadiabatic coupling can be described in terms of the Riemannian parallel transport of their geometriccounterparts in the space of control parameters. The results of mathematical modeling of nonadiabaticeffects, presented in the paper for the case of four-level systems interacting with three laser fields (tripodsystems), demonstrate full agreement between the quantum and geometric approaches. These results areof interest for experimental and laboratory plasma research and atomic and laser physics.
