Usually, an unfocused light beam, such as a paraxial Gaussian beam, can exert a force on
an object along the direction of light propagation, which is known as light pressure …

Polarization singularities and topological vortices in photonic crystal slabs centered at
bound states in the continuum (BICs) can be attributed to zero amplitude of polarization …

Specialized electromagnetic fields can be used for nanoparticle manipulation along a
specific path, allowing enhanced transport and control over the particle's motion. In this …

Undoubtedly, laser tweezers are the most recognized application of optically induced
mechanical action. Their operation is usually described in terms of conservative forces …

The ever‐growing field of microfluidics requires precise and flexible control over fluid flows
at reduced scales. Current constraints demand a variety of controllable components to carry …

Optical forces is a unique phenomenon derived from light–matter interaction. It took
centuries before people were finally able to measure, and manipulate this extremely tiny …

In this paper, we are concerned with chirped solitary wave solutions in negative indexed
materials having Kerr nonlinearity and self-phase modulation term. An auxiliary equation …

Optical binding allows creation of mechanically stable nanoparticle configurations owing to
formation of self-consistent optical trapping potentials. While the classical diffraction limit …

We achieve long-range and continuous optical pulling in a periodic photonic crystal
background, which supports a unique Bloch mode with the self-collimation effect. Most …

The debate and controversy concerning the momentum of light in a dielectric medium
(Abraham vs Minkowski) is well-known and still not fully resolved. In this paper, we …
