The properties of quantum materials far from equilibrium will be studied by means of a multi-stimulus scheme, in which low-lying excitations are driven by means of intense microwave radiation while monitoring the response with a second probe. The approach aims to (i) identify the coupling of spin, orbital, lattice, or nuclear degrees of freedom under intense resonant microwave radiation, (ii) achieve tailored driving of quantum excitations such as topological magnons, orbitons, or electronic topological quasiparticles, (iii) create non-thermal melting of long-range order by intense microwave radiation, and (iv) realize the formation of dynamical forms of quantum order in bulk materials such as time crystals or many-body-localization.
