In this Letter, we propose a kind of controllable multi-spiral beam that can be generated using the modulated helico-conical phases with an axicon. The focal-field intensity distributions beams were investigated theoretically and experimentally. relative distance between two adjacent sub-beams was discussed based on approximate mapping local spatial frequency. result demonstrated linearly dependent radial factor gradient Δα sub-beams. When is equal to critical value (i.e., Δαc), changed into...
Twisted spin waves (or twisted magnons, TMs) have significant potential in high-capacity communication due to their orbital angular momentum (OAM) degree of freedom. Consequently, manipulating the propagation TMs has become an important topic spintronics. Here, we theoretically study band structures ferromagnetic cylindrical magnonic crystals with periodically modulated anisotropy. We find that arbitrary OAMs exhibit forbidden bands at boundary Brillouin zone, though, different frequency...
We propose a method for measuring the photonic topological charge of power-exponent-phase vortex (PEPV) beam with cross phase. Based on superimposition power-exponent phase and phase, we analyzed axial diffraction properties modulated PEPV different parameters by using scalar theory. The simulations demonstrated that dark regions are embedded in intensity profile beam, number is just equal to carried beam. Moreover, sign can be distinguished alignment direction light field. experimental...

Twisted magnons (TMs) have great potential applications in communication and computing owing to the orbital angular momentum degree of freedom. Realizing unidirectional propagation TMs is key designing functional magnonics devices. Here we theoretically study one-dimensional magnetic nanodisk arrays. By performing micromagnetic simulations, find that array exhibits a few bands due collective excitations TMs. A simple model exchange interaction proposed explain emerging multiband structure,...
The interaction between propagating magnons and topological spin textures is attracting a lot of recent attention from the magnonic community. It has been shown that three-wave mixing breathing skyrmion can induce magnon frequency comb (MFC) with equidistant coherent peaks. However, magnetic bimeron nontrivial texture regarded as counterpart in easy-plane magnets Dzyaloshinskii–Moriya interaction, which allows anisotropic propagations. This raises question whether nonlinear bimerons generate...
A stable, low-power, and tunable magnon frequency comb (MFC) is crucial for magnon-based precision measurements, quantum information processing, chip integration. The original method creating a MFC utilizes the nonlinear interactions between propagating spin waves localized oscillations of an isolated magnetic texture, e.g., skyrmion. It requires driving well above ferromagnetic resonance (FMR) spectrum will quickly approach detection limit conventional microwave technique after only tens...
Magnetic skyrmions, with their topologically stable magnetic textures, exhibit unique properties that make them attractive options for processing and storing information in spintronic devices. In this study, we employ micromagnetic simulations to explore the motion of skyrmion dependence on Gilbert damping coefficient by spin-wave (SW) when a field is present along z - direction. We found that, choosing larger makes more minimize amount computation required. It important acknowledge actual...
