Super-resolution optical microscopy, which gives access to finer details of objects, is highly
desired for fields of nanomaterial, nanobiology, nanophotonics, etc. Many efforts, including …

Modern nanotechnology demands advanced microscopy with ever finer resolution and
detectivity of both explicit and inexplicit features of matter. While typical optical microscopy …

Light with helical phase wavefront carries orbital angular momentum, a unique feature
widening the horizon of optical imaging applicability. Here, we take particular interest in the …

The photothermal effect in nanomaterials, resulting from resonant optical absorption, finds
wide applications in biomedicine, cancer therapy, and microscopy. Despite its prevalence …

Benefiting from the unprecedented superiority of coding metasurfaces at manipulating
electromagnetic waves in the microwave band, in this paper, we use the Pancharatnam …

We introduce the universal upper bound of helicity density, which is the maximum helicity
light can have at a given light energy density. Helicity maximization as discussed here is …

The microscopic structure of the material's solid–liquid interface significantly influences its
physicochemical properties. Peak force infrared microscopy (PFIR) is a powerful technique …

Optical spin and orbital angular momenta are intrinsic characteristics of light determined by
its polarization and spatial degrees of freedom, respectively. At the nanoscale, sharply …

Recent work has shown that optical magnetism, generally considered a challenging light–
matter interaction, can be significant at the nanoscale. In particular, the dielectric …

Nonradiating current configurations have been drawing the attention of the physics
community for many years. It has been demonstrated recently that dielectric nanoparticles …
