A variety of magnetic particles with unique topology have been explored since the
experimental discovery of magnetic skyrmions. Those topologically-nontrivial spin-twisting …

Mn x Ge1–x quantum dots (QDs), with a high Curie temperature and superior magnetic
properties, have significant application and research values for spintronic devices for high …

The phonon magnetochiral effect (MChE) is the nonreciprocal acoustic and thermal
transports of phonons caused by the simultaneous breaking of the mirror and time-reversal …

Hedgehog and antihedgehog spin textures in magnets behave as emergent monopoles and
antimonopoles, which give rise to astonishing transport and electromagnetic phenomena …

Nonlinear electrodynamics in materials manifests as an electronic response that depends
on second-or higher-order powers of the applied electromagnetic field. This response is …

Chiral magnets under broken time-reversal symmetry can give rise to rectification of moving
electrons, called nonreciprocal transport. Several mechanisms, such as the spin-fluctuation …

Recently, nonlinear responses have been actively studied in both experiments and theory.
Particularly interesting are inversion-symmetry broken systems, where an even-order …
