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

Researchers at the University of Erlangen-Nuremberg, Germany have produced a novel light beam that possesses angular momentum ... with opposing spin (one is left circularly polarized, whereas ...

Or one might employ circularly polarized light to selectively influence ... "Furthermore, coupling between orbital angular momentum and spin could allow integration into existing spintronics ...

Recently, the manipulation of the spin angular momentum (SAM)—or polarization—of these attosecond pulses has been extensively explored [1] - [3] . In particular, circularly polarized attosecond pulses ...

As fast as modern electronics have become, they could be much faster if their operations were based on light, rather than ...

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the ...

a quarter-wave plate that converts the Stokes beam 120S to a circular or elliptical polarization. 35 The probe laser 110 pr in FIG. 2 may produce linearly 40 polarized light, and the waveplate ...

Impact Statement: In this work, a significantly simplified circular polarization ceramic antenna array is employed to generate orbital angular momentum (OAM) beams without the assistance of phase ...

Our results indicate that this phenomenon can be attributed to the formation of photon-spin-dependent lattice modes when these arrays interact with circularly polarized light. In the metasurfaces ...
