AbstractThe eigenvalue problem of a time-periodic driven two-level system is investigated. The closed-form solutions for the quasienergy and the Floquet states are obtained with the help of SU(2) symmetry. A distinct advantage of this approach is that the calculations of physical quantities can be made up to any order approximations straightforwardly. To illustrate the validity of our method, we present detailed calculations for a biased double-well heterostructure driven by a laser field. Various situations for the ratio of the energy gap of the undriven system to the laser frequency are discussed, among which it is found that the exact quasienergy crossing emerges if this ratio becomes a nonzero even number. Such an effect of localization should be observable in experiments.
