Optical activity is conventionally understood as a natural difference in the optical responses
of chiral materials with opposite handedness. It stems from the quantised spin angular …

Orbital angular momentum (OAM) of light is an important feature of structured
electromagnetic fields exhibiting non-uniform spatial distribution. In contrast to a spin …

Abstract Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or
polarization upon reflection from or transmission through a magnetic sample, were …

Magneto-optics (MO) is an effervescent research field, with a wide range of potential
industrial applications including sensing, theranostics, pharmaceutics, magnetometry, and …

We demonstrate the spin to orbital angular momentum transfer in frequency upconversion
with structured light beams. A vector vortex is coupled to a circularly polarized Gaussian …

We report on the experimental evidence of magnetic helicoidal dichroism, observed in the
interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a …

In this work we study the evolution of an optical vortex undergoing self-phase modulation
inside a nonlinear Kerr medium. The intensity-dependent phase evolution couples the …

High harmonic generation (HHG) has become a core pillar of attosecond science.
Traditionally described with field-based models, HHG can also be viewed in a parametric …

X-ray beams carrying orbital angular momentum (OAM) are an emerging tool for probing
matter. Optical elements, such as spiral phase plates and zone plates, have been widely …

Electromagnetic waves possessing orbital angular momentum (OAM) are powerful tools for
applications in optical communications, quantum technologies, and optical tweezers …
