A stack of a dielectric planar waveguide with a Kerr-type nonlinearity, sandwiched between
two oxide-based helical multiferroic layers is shown to support electrically-controlled chiral …

Chirality is inherent to a broad range of systems, including solid-state and wave physics. The
precession (chiral motion) of the magnetic moments in magnetic materials, forming spin …

This study demonstrates that the magnetic quadrupole (MQ) can make an indispensable
contribution to helical dichroism (HD), which is distinct from HD caused by electric …

Material anisotropy and chirality produce polarization-dependent light-matter interactions.
Absorption leads to linear and circular dichroism, whereas elastic forward scattering …

The chiral light field has attracted great attention owing to its interaction with chiral matter.
The generation of chiral light fields with rich structures has become crucial as it can expand …

X-ray vortices carrying tunable orbital angular momentum (OAM) are an emerging tool for x-
ray characterization. However, in contrast to the generation of vortex beams in the visible …

Recently, novel chiroptical harmonic scattering effects were reported, and the associated
techniques have emerged as promising tools for characterizing the chirality of light …

Material anisotropy produces differential absorption and birefringence of linearly polarized
light; material chirality leads to differential absorption and birefringence of circularly …

Optical vortices are beams of laser light in which photons are conveyed with a helical
wavefront. With a corresponding azimuthal dependence in optical phase, their screw …
