| Research Abstract |
In the present study, the theoretical investigation has been planned, aimed at examining quasi-energy structures of atoms under crossed ac- and dc- magnetic fields, and at exploring the possibility of quantum control of the associated states with an anomalous character with respect to parameters of the oscillating magnetic field such as its peak strength and frequency. We have developed a new method of numerical calculations complete with sufficient efficiency, by which a necessity of a large-scaled computation for the physical system of concern is remedied. Further, it is found that there is a physical analogy and a relation with the phenomenon of dynamic Wannier-Stark ladder in semiconductor superlattices.
