Magnonics addresses the dynamic excitations of a magnetically ordered material. These
excitations, referred to as spin waves and their quanta, magnons, are a powerful tool for …

Cavity magnonics deals with the interaction of magnons—elementary excitations in
magnetic materials—and confined electromagnetic fields. We introduce the basic physics …

Engineered quantum systems enabling novel capabilities for computation and sensing have
blossomed in the last decade. Architectures benefiting from combining complementary …

Photons at microwave and optical frequencies are principal carriers for quantum information.
While microwave photons can be effectively controlled at the local circuit level, optical …

We report the first observation of the magnon-polariton bistability in a cavity magnonics
system consisting of cavity photons strongly interacting with the magnons in a small yttrium …

Magnon–polaritons are hybrid light–matter quasiparticles originating from the strong
coupling between magnons and photons. They have emerged as a potential candidate for …

Multistability is an extraordinary nonlinear property of dynamical systems and can be
explored to implement memory and switches. Here we experimentally realize the tristability …

We propose a scheme to entangle two magnon modes via the Kerr nonlinear effect when
driving the systems far from equilibrium. We consider two macroscopic yttrium iron garnets …

We present a scheme to entangle two magnon modes in a cavity magnomechanical system.
The two magnon modes are embodied by collective motions of a large number of spins in …

Cavity optomagnonics has emerged as a promising platform for studying coherent photon-
spin interactions as well as tunable microwave-to-optical conversion. However, current …
