Observation of topological charge transformations in acoustic vortex using passive periodic systems

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 140-147页

作者： Di-Chao chen Xie Liu Changqing Xu Da-Jian Wu Ying cheng Xiao-Jun Liu School of Physics and Technology Nanjing Normal University Key Laboratory of Modern Acoustics School of Physics Nanjing University

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.

基于雨生红球藻游动细胞和不动细胞间Triton X-100敏感性的差异,建立了一种快速监测培养过程中细胞分化的指标,对比了雨生红球藻在BG11和BBM两种培养基中的细胞生长与分化差异.结果表明,在BBM培养基中培养8 d,雨生红球藻的游动细胞比例始终较高,而在BG11中早期不动孢子囊释放的游动孢子则快速成熟并转变成不动细胞.这主要是由于BBM中游动细胞通过有丝分裂或孢子囊两种模式维持了其继续分裂与增殖的能力,而BG11中这些繁殖形式缺失的主要原因在于其较低的磷浓度,培养基中适当的高磷含量对保持雨生红球藻培养中期游动细胞的持续繁殖非常关键.
