The paradigm of the two-level atom is revisited and its perturbative analysis is discussed in
view of the principle of duality in perturbation theory. The models we consider are a two …

The calculation of the Floquet quasi-energies of a system driven by a time-periodic field is
an efficient way to understand its dynamics. In particular, the phenomenon of dynamical …

Analytical expressions for the semiclassical dressed states and corresponding
quasienergies are obtained for a two-level quantum system driven by a non-resonant and/or …

Using perturbation theory in the strong coupling regime, that is, the dual Dyson series, and
renormalization-group techniques to resum secular terms, we obtain the perturbation series …

We present results on the occurrence of high-order harmonic generation in a two-electron
quantum dot molecule. The two-electron quantum dot molecule consists of two interacting …

Non-perturbative, exact analytical results are obtained for the harmonically driven two-level
system with the use of a Floquet–Green operator formalism. From this operator, we find the …

It is shown analytically that there exists a natural basis in terms of which the nonperturbative
time evolution of an important class of driven four-level systems in the strong-coupling …

We investigate analytically and numerically the emission spectrum of a two-electron
quantum dot molecule in a continuous wave driving electromagnetic field. For high …

We apply the method of Lie-type transformations to Floquet Hamiltonians for periodically
perturbed quantum systems. Some typical examples of driven quantum systems are …
