Extended Data Fig. 5: Unstable trapping of floating particles.
From: Topological water-wave structures manipulating particles
Dynamics of a floating particle with radius a = 4.75 mm in the Bessel-vortex wave with \({\ell }=2\). Unlike Fig. 4c in the main text, here the particle is attracted to the intensity-maximum ring, orbits there for some time, and then escapes, because the radial centrifugal force prevails the trapping gradient force.
