CONCEPT

Coupled Chladni modal eigenfunctions drive acoustic radiation pressure across an anisotropic clamped plate, trapping granular ash along bifurcating nodal curves and streaming vortex cells. 与邻近位错裂解晶格形成声学共振对照,高频超声辐射力将微晶碎屑驱赶至模态跳变驻波节线中沉淀。

LORE

The bedrock beneath the terrace developed an ultrasonic hum, vibrating against the cleaved slip-planes of the lattice next door. 悬浮的火山灰不再随风漫流,而是被声辐射压强迫归位,在固支边界间沉淀为锋利的克拉尼节线网格 (Chladni nodal lines).

JOURNAL

Coupled $m,n \in [2, 7]$ modal eigenfunctions on a rectangular boundary with anisotropic tension. By deriving the time-averaged Gor'kov radiation potential rather than advecting discrete particles, the field drives density from background diffuse states directly into narrow attractor ridges (density peaked at 0.945 during bifurcation). Mode-switching intervals produce clean topological reconnection of zero-velocity lines.
