Vortex formation around islands in random waves
Alex J. Vernon, Junyi Ye, Wenzhe Liu +2
Wave vortices are fundamental topological features of interference fields, occurring at nodal points where the wave amplitude vanishes. A distinct class of vortices can instead for…
Radiation forces and torques in optics and acoustics
Ivan Toftul, Sebastian Golat, Francisco J. RodrÃguez-Fortuño +3
The mechanical action of various kinds of waves has been recognized for several centuries. The first tide of scientific interest in wave-induced forces and torques emerged at the t…
Wave Vortices Around Oscillating Subwavelength Holes: Water-Wave Observation
Junyi Ye, Zheyi Li, Alexey Y. Nikitin +4
We consider a two-dimensional wave system containing a subwavelength hole, such as an aperture in an interface supporting surface electromagnetic or acoustic waves, or an island in…
Dynamic Water-Wave Tweezers
Jun Wang, Shanhe Pang, Zhiyuan Che +8
Following a recent demonstration of stable trapping of floating particles by stationary (monochromatic) structured water waves [Nature 638, 394 (2025)], we report dynamic water-wav…
Time-diffracting 2D wave vortices
Boris A. Khanikati, Konstantin Y. Bliokh
Wave vortices constitute a large family of wave entities, closely related to phase singularities and orbital angular momentum (OAM). So far, two main classes of localized wave vort…
Electric-Magnetic Geometric Phase
Alex J. Vernon, Konstantin Y. Bliokh
Geometric phases play an enormous role in optics and are generally associated with the evolution of light's polarization state on the Poincaré sphere, or its spin on the sphere of…
