On-chip Dicke-type magnon polaritons in the ultrastrong coupling regime via spatially separated nanomagnets
Shugo Yoshii, Manuel Müller, Ryo Ohshima +4
Quantum electrodynamics lies at the heart of hybrid quantum systems essential for future technologies. The thermodynamic limit of the Dicke model, a fundamental model describing th…

Theory of polarization-dependent phonon pumping in ferromagnetic/non-magnetic bilayers
Mikhail Cherkasskii, Fabian Engelhardt, Manuel Müller +5
We develop a theoretical model for polarization-selective phonon pumping induced by magnon-phonon coupling in a ferromagnetic/non-magnetic acoustic bilayer structure, focusing on t…

Temperature-dependent spin-transport and current-induced torques in superconductor/ferromagnet heterostructures
Manuel Müller, Lukas Liensberger, Luis Flacke +6
We investigate the injection of quasiparticle spin currents into a superconductor via spin pumping from an adjacent FM layer.To this end, we use NbN/\ch{Ni80Fe20}(Py)-heterostr…
