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 …

Light–matter interactions lie at the heart of condensed matter physics, providing physical
insight into material behavior while enabling the design of new devices. Perhaps this is most …

Spin waves in magnetic insulators are low‐damping signal carriers that can enable a new
generation of spintronic devices. The excitation, control, and detection of spin waves by …

The inevitable Gilbert damping in magnetization dynamics is usually regarded as
detrimental to spin transport. Here we apply a general feature of chiral non-Hermitian …

Interference between coherent and dissipative coupling results in nonreciprocity in cavity
magnonic devices, in which the isolation ratio can theoretically be infinite when the magnon …

We directly measure the low energy excitation modes of the quantum Ising magnet LiHoF 4
using microwave spectroscopy. Instead of a single electronic mode, we find a set of …

The inevitable Gilbert damping in magnetization dynamics is usually regarded as
detrimental to spin transport. Here we demonstrate in a ferromagnetic-insulator--normal …

Exceptional points with coalescence of eigenvalues and eigenvectors are spectral
singularities in the parameter space, achieving which often needs fine-tuning of parameters …

Achieving quantum-level control over electromagnetic waves, magnetisation dynamics,
vibrations, and heat is invaluable for many practical applications and possible by exploiting …

We have proposed and demonstrated the hybridization between magnon modes of a
magnetic vortex pair (MVP) of opposite chirality. The proposed magnon hybridization in MVP …
