Topological insulators and semimetals in classical magnetic systems
Z. -X. Li, Yunshan Cao, Peng Yan
Pursuing topological phases in natural and artificial materials is one of the central topics in modern physical science and engineering. In classical magnetic systems, spin waves (…
Strong coupling of quantized spin waves in ferromagnetic bilayers
Zhizhi Zhang, Huanhuan Yang, Zhenyu Wang +2
We formulate a strong-coupling theory for perpendicular standing spin waves (PSSWs) in ferromagnetic bilayers with the interlayer exchange coupling (IEC). Employing the Hoffmann bo…
Robust edge states in magnetic domain-wall racetrack
Z. -X. Li, Zhenyu Wang, Yunshan Cao +2
Controllable artificial pinning is indispensable in numerous domain-wall (DW) devices, such as memory, sensor, logic gate, and neuromorphic computing hardware. The high-accuracy de…
Spin-wave focusing induced skyrmion generation
Zhenyu Wang, Z. -X. Li, Ruifang Wang +4
We propose a new method to generate magnetic skyrmions through spin-wave focusing in chiral ferromagnets.A lens is constructed to focus spin waves by a curved interface between two…
Realization of the square-root higher-order topological insulator in electric circuits
Lingling Song, Huanhuan Yang, Yunshan Cao +1
Higher-order topological insulator (HOTI) represents a new phase of matter, the characterization of which goes beyond the conventional bulk-boundary correspondence and is attractin…
Negative Gilbert damping in cavity optomagnonics
Yunshan Cao, Peng Yan
Exceptional point (EP) associated with the parity-time (PT) symmetry breaking is receiving considerable recent attention by the broad physics community. By introducing balanced gai…
