Optical manipulations utilizing the mechanical effect of light have been indispensable in
various disciplines. Among those various manipulations, optical pulling has emerged …

Because of analogies between the 2D Maxwell equations and water wave equations,
methods for manipulating electromagnetic waves based on photonic crystals and …

Structured waves are ubiquitous for all areas of wave physics, both classical and quantum,
where the wavefields are inhomogeneous and cannot be approximated by a single plane …

Liquid droplets have been studied for decades and have recently experienced renewed
attention as a simplified model for numerous fascinating physical phenomena occurring on …

Topological wave structures—phase vortices, skyrmions, merons, etc.—are attracting
enormous attention in a variety of quantum and classical wave fields. Surprisingly, these …

Motivated by recent progress in the generation of optical spatiotemporal vortex pulses
(STVPs), there is a theoretical discussion about the transverse orbital angular momentum …

Acoustics-based tweezers provide a unique toolset for contactless, label-free, and precise
manipulation of bioparticles and bioanalytes. Most acoustic tweezers rely on acoustic …

Abstract 2D colloidal crystallization provides a simple strategy to produce defined
nanostructure arrays over macroscopic areas. Regularity and long‐range order of such …

Spin is a fundamental yet nontrivial intrinsic angular momentum property of quantum
particles or fields, which appears within relativistic field theory. The spin density in wave …

We construct a novel Lagrangian representation of acoustic field theory that describes the
local vector properties of longitudinal (curl-free) acoustic fields. In particular, this approach …
