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

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

It has been recently shown that in the Heisenberg (anti) ferromagnet on the honeycomb
lattice, the magnons (spin wave quasipacticles) realize a massless two-dimensional (2D) …

Topological magnons are bosonic analogues of topological fermions in electronic systems.
They have been studied extensively by theory but rarely realized by experiment. Here, by …

Transport in non-Hermitian quantum systems is studied. The goal is a better understanding
of transport in non-Hermitian systems like the Lieb lattice due to its flat bands and the …

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

Quite recently, the magnon Hall effect of spin excitations has been observed experimentally
on the kagome and pyrochlore lattices. The thermal Hall conductivity κ xy changes sign as a …

We review recent developments in theories and experiments on the magnon Hall effect. We
derive the thermal Hall conductivity of magnons in terms of the Berry curvature of magnonic …

We establish theoretically a thermal Hall effect of collective magnetic excitations in
noncollinear but coplanar antiferromagnets. In agreement with superordinate symmetry …

Topological magnon is a vibrant research field gaining more and more attention in the past
few years. Among many theoretical proposals and limited experimental studies …
