Abstract
Spatially uniform optical excitations can induce Floquet topologicalband structures withininsulators which can develop similar or equal characteristics as areknown from three-dimensional topological insulators. We derive in thisarticle theoretically the development of Floquet topological quantumstates for electromagnetically driven semiconductor bulk matter and wepresent results for the lifetime of these states and their occupationin the non-equilibrium. The direct physical impact of the mathematicalprecision of the Floquet-Keldysh theory is evident when we solve thedriven system of a generalized Hubbard model with our framework ofdynamical mean field theory (DMFT) in the non-equilibrium for a caseof ZnO. The physical consequences of the topological non-equilibriumeffects in our results for correlated systems are explained with theirimpact on optoelectronic applications.
