Manifestation of anomalous Floquet states with longevity in dynamic fractional Stark ladder with high AC electric fields

Yuya Nemoto, Fumitaka Ohno, Nobuya Maeshima +1

We examine a resonance structure of Floquet state in dynamic fractional Stark ladder (DFSL) realized in biased semiconductor superlattices driven by a terahertz cw laser on the bas…
