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

Magnonics addresses the physical properties of spin waves and utilizes them for data
processing. Scalability down to atomic dimensions, operation in the GHz-to-THz frequency …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Hybrid dynamic systems have recently gained interest with respect to both fundamental
physics and device applications, particularly with their potential for coherent information …

The dipole approximation is usually employed to describe light-matter interactions under
ordinary conditions. With the development of artificial atomic systems,'giant atom'physics is …

The spontaneous magnetic orders arising in ferro-, ferri-and antiferromagnets stem from
various magnetic interactions. Depending on the interplay and competition among the …

Dynamical backaction resulting from radiation pressure forces in optomechanical systems
has proven to be a versatile tool for manipulating mechanical vibrations. Notably, dynamical …

Chirality or handedness distinguishes an object from its mirror images, such as the spread
thumb, index finger, and middle finger of the right and left hand. In mathematics, it is …

By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise
eigenspace controllability, we observe two different singularities in the same system. One …
