Spectroscopic determination of Floquet quasi-energies

ABSTRACT

It is shown that the quasi-energies (the exponents’ time coefficients) of multi-component Floquet functions can be determined (up to sign) by spectroscopic, (non-interferometric) means, from the probability peaks in inter-component optical transitions. A previous, related work was based on time-correlation in Floquet systems.
