For a physicist, and more generally for a scientist, one of the pleasures in everyday life is to
detect exemplifying manifestations and avatars of the topic he is working on. Why do small …

We analyze microparticle dynamics within a “perfect” vortex beam. In contrast to other vortex
fields, for any given integer value of the topological charge, a “perfect” vortex beam has the …

We analyze the interference field formed by two electromagnetic plane waves (with the
same frequency but different wave vectors), and find that such a field reveals a rich and …

Relying on the time averaged Poynting vector expressed in terms of beam shape
coefficients, dark and superdark theorems are discussed generalizing a previously …

Vortex beam propagates in the atmospheric environment, it interacts with the floating cloud,
fog, rain and other micro particles, the absorption and scattering effects will lead to the …

We customize a transversely structured, tunable light landscape on the basis of orbital
angular momentum (OAM)-carrying beams for the purpose of advanced optical …

We examine acoustic radiation force and torque on a small (subwavelength) absorbing
isotropic particle immersed in a monochromatic (but generally inhomogeneous) sound-wave …

We analyse the ponderomotive action experienced by a small spherical particle immersed in
an optical field, in relation to the internal energy flows (optical currents) and their spin and …

One of the key trends in laser material processing is the usage of structured laser beams.
Collimated and focused Gaussian beams are the most common tools; however, more exotic …

Based on the generalized Lorenz-Mie theory and Maxwell stress tensor formulism, we
calculate the transverse force constant matrix and perform a linear stability analysis on a …
