Antiferromagnetic Resonance Revisited: Dissipative Coupling without Dissipation
Yutian Wang, Jiang Xiao
The antiferromagnet is a closed Hermitian system, we find that its excitations, even in the absence of dissipation, can be viewed as a non-Hermitian system with dissipative couplin…
Electrically Switchable van der Waals Magnon Valves
Guangyi Chen, Shaomian Qi, Jianqiao Liu +14
Van der Waals magnets have emerged as a fertile ground for the exploration of highly tunable spin physics and spin-related technology. Two-dimensional (2D) magnons in van der Waals…
Spin wave driven domain wall motion in easy-plane ferromagnets: a particle perspective
Jin Lan, Jiang Xiao
In easy-plane ferromagnets, we show that the interplay between a domain wall and a spin wave packet can be formulated as the collision of two massive particles with a gravity-like…
Narrow waveguide based on ferroelectric domain wall
Gongzheng Chen, Jin Lan, Tai Min +1
Ferroelectric materials are spontaneous symmetry breaking systems characterized by ordered electric polarizations. Similar to its ferromagnetic counterpart, a ferroelectric domain…
A Hopfield neural network in magnetic films with natural learning
Weichao Yu, Jiang Xiao, Gerrit E. W. Bauer
Macroscopic spin ensembles possess brain-like features such as non-linearity, plasticity, stochasticity, selfoscillations, and memory effects, and therefore offer opportunities for…
