The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists at Forschungszentrum Jülich have now ...

Light beams carrying orbital angular momentum (OAM) can be generated in the extreme ultraviolet and soft X-ray spectra by means of high harmonic generation (HHG). In HHG, phase properties of the drive ...

Since the Moment of Inertia I now increases, ω decreases to keep the Angular Momentum L = Iω a constant, leading to a decreasing angular acceleration ∝ ∝ of the Universe, until it reaches a constant ...

The superposition of two light beams with different amplitudes carrying only negative orbital angular momentum (OAM) gives rise to a locally positive OAM in the dark regions.

The superposition of two light beams with different amplitudes carrying only negative orbital angular momentum (OAM) gives rise to a locally positive OAM in the dark regions.

Unlocking the potential of orbital angular momentum (OAM) of electromagnetic waves has advanced thanks to persistent research efforts globally. As reported in Advanced Photonics, researchers from ...

Impact Statement: Orbital angular momentum (OAM) offers a new dimension of space mode, because coaxially propagating OV beams with different azimuthal OAM states are mutually orthogonal. Therefore, up ...

Structured light beams such as optical vortices can carry the orbital angular momentum (OAM) with an unbounded quantum number. Recent years have witnessed a growing interest in the rotational Doppler ...

The cylindrical lens brings the orbital angular momentum (OAM) into the original Hermite-Gaussian (HG) beam. The OAM of such a beam is the sum of the vortex and astigmatic components, and can reach ...

Proper tuning enhances polarization purity and generates a circularly polarized outgoing wave with orbital angular momentum. The scientists used an x-polarized beam incident on a 16-by-16 array of ...
