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

The long fascination that antiferromagnetic materials has exerted on the scientific community
over about a century has been entirely renewed recently with the discovery of several …

Two-dimensional (2D) van der Waals (vdW) magnets have been a fertile playground for the
discovery and exploration of physical phenomena and new physics. In this Letter, we report …

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 …

We demonstrate theoretically that the thermal Hall effect of magnons in collinear
antiferromagnetic insulators is an indicator of magnetic and topological phase transitions in …

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

In the recent years, the thermal Hall transport has risen as an important diagnosis of the
physical properties of the elementary excitations in various quantum materials, especially …

The discovery of magnetism by the ancient Greeks was enabled by the natural occurrence of
lodestone–a magnetized version of the mineral magnetite. Nowadays, natural minerals …

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

We theoretically study the topological properties of the tight-binding model on the breathing
kagome lattice with antisymmetric spin-orbit coupling (SOC) between nearest neighbors. We …
