ResearchHybrid Systems
At the Walther-Meissner-Institute we pioneered research in the direction of strong magnon-photon interaction, which is key to investigate magnons on the quantum level, but also gives deep insight in the hybridization of magonic and phonic states, an aspect which we have intensely researched by combining this hybrid system with electical readout techniques.
Spin ensembles based on paramagnetic centers are complementary to their exchange coupled counterpart. Although, the coupling is less intense, they still can be operated in the strong coupling regime. Due to their extreme coherence times, these spin systems are discussed for quantum memory or quantum transduction applications.
In addition, we study magnon-phonon hybrids based on acoustic resonators and magnetic thin films, as well as coupled nano-string resonator networks.
