Chirality is pivotal in nature which attracts wide research interests from all disciplines and
creating chiral matter is one of the central themes for chemists and material scientists …

Coupling between light and material excitations underlies a wide range of optical
phenomena. Polaritons are eigenstates of a coupled system with a hybridized wave …

In this work we undertake a systematic study of the optical chirality density of Laguerre-
Gaussian and Bessel laser beams tightly focused into nanoscale volumes. In particular we …

Like energy and momentum, optical helicity is a fundamental dynamical property of light. In
the prevalent plane wave and paraxial description of light the optical helicity is directly …

Recently, a variety of mechanisms have been discovered that extend the range of optical
techniques for identifying and characterizing molecular chirality, beyond those associated …

We derive the analytical expressions of the electric and magnetic field vectors as well as
optical chirality density of tightly focused higher-order Poincaré sphere (HOPS) vector vortex …

Here, we describe a systematic derivation of the general form of the optical helicity density of
ellipticaly polarized paraxial Laguerre–Gaussian modes LG_ℓ, p, σ. The treatment …

Transmission electron microscopy can be described in terms of the measurement, in an
appropriate quantum basis, of the quantum state of an electron after scattering through a …

Recent work has confirmed that radially-polarised optical modes, specifically those
endowed with helical wave fronts can now be routinely generated in the laboratory. Here we …
