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

The concept of chirality is of great relevance in nature, from chiral molecules such as sugar
to parity transformations in particle physics. In condensed matter physics, recent studies …

Abstract Two-dimensional (2D) magnetic systems possess versatile magnetic order and can
host tunable magnons carrying spin angular momenta. Recent advances show angular …

Topological phonons and magnons potentially enable low-loss, quantum coherent, and
chiral transport of information and energy at the atomic scale. Van der Waals magnetic …

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 …

We study the interaction of surface acoustic waves with spin waves in ultrathin CoFeB/Pt
bilayers. Because of the interfacial Dzyaloshinskii–Moriya interaction (DMI), the spin wave …

Magnetic order typically emerges due to the short-range exchange interaction between the
constituent electronic spins. Recent discoveries have found a crucial role for spin-phonon …

We theoretically investigate magnon-phonon hybrid excitations in two-dimensional
ferromagnets. The bulk bands of hybrid excitations, which are referred to as magnon …

Chiral symmetry breaking of phonons plays an essential role in emergent quantum
phenomena owing to its strong coupling to spin degree of freedom. However, direct …

Magnon polarons, a type of hybridized excitations between magnons and phonons, were
first reported in yttrium iron garnet as anomalies in the spin Seebeck effect responses. Here …
