At sufficiently low temperatures, magnetic materials often enter correlated phases hosting
collective, coherent magnetic excitations such as magnons or triplons. Drawing on the …

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 …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

Condensed matter systems admit topological collective excitations above a trivial ground
state, an example being Chern insulators formed by Dirac bosons with a gap at finite …

Recently, topolectrical circuits (TECs) boom in studying the topological states of matter. The
resemblance between circuit Laplacians and tight-binding models in condensed matter …

The glycosides of two flavonoids, naringin and naringenin, are found in various citrus fruits,
bergamots, tomatoes, and other fruits. These phytochemicals are associated with multiple …

Topological magnon insulators (TMI) are ordered magnets supporting chiral edge magnon
excitations. These edge states are envisioned to serve as topologically protected information …

Magnonics or magnon spintronics is an emerging field focusing on generating, detecting,
and manipulating magnons. As charge‐neutral quasi‐particles, magnons are promising …

We consider two distant spin qubits in quantum dots, both coupled to a two-dimensional
topological ferromagnet hosting chiral magnon edge states at the boundary. The chiral …

We study magnon excitations and their interactions in honeycomb antiferromagnets with the
Dzyaloshinskii-Moriya interaction. When an applied magnetic field is turned on, the classical …
