​The groups of Stefan Linden and Hans Kroha published their recent results within the Focus Area 4.1 in this paper which was accepted for publication in Nature Communications. In “Observation of topological transport quantization by dissipation in fast Thouless pumps”, the authors introduce non-Hermitian Floquet engineering as a new concept to overcome the restriction of quantizes Thouless pumping to the limit of slow driving. The authors predict that a topological band structure and associated quantized transport can be restored at driving frequencies as large as the system’s band gap. The underlying mechanism is suppression of non-adiabatic transitions by tailored, time-periodic dissipation. (Picture: Zlata Fedorova; published on LinkedIn)
