Magnon frequency comb (MFC), the spin-wave spectra composing of equidistant coherent peaks, is attracting much attention in magnonics. A terahertz (THz) MFC, combining the advantages of the THz and MFC technologies, is highly desired because it would

Nonlinear Topological Magnon Spin Hall Effect

Autor: Jin, Zhejunyu, Yao, Xianglong, Wang, Zhenyu, Yuan, H. Y., Zeng, Zhaozhuo, Cao, Yunshan, Yan, Peng

When a magnon passes through two-dimensional magnetic textures, it will experience a fictitious magnetic field originating from the $3\times 3$ skew-symmetric gauge fields. To date, only one of the three independent components of the gauge fields has

Competition of non-Hermitian skin effect and topological localization of corner states observed in circuits

Autor: Tang, Chan, Yang, Huanhuan, Song, Lingling, Yao, Xianglong, Yan, Peng, Cao, Yunshan

Exploring topological phases in non-Hermitian systems has attracted significant recent attention. One intriguing question is how topological edge states compete with the non-Hermitian skin effect. Here, we report the experimental observation of corne

Publikováno v: Front. Phys. 9, 729967 (2021)

We propose a method to generate magnetic skyrmions by focusing spin waves totally reflected by a curved film edge. Based on the principle of identical magnonic path length, we derive the edge contour that is parabolic and frequency-independent. Micro
