Scientists have cracked a century-old physics mystery by detecting magnetic signals in non-magnetic metals using only light ...

Recent findings confirm the conservation of orbital angular momentum in single-photon interactions, reinforcing fundamental ...

On the whole, regardless of the filamentation condition, in the high-input intensity region more efficient largely anisotropic THz vortex beam with more refinement intensity and highly orbital angular ...

The destroyer Preble successfully test-fired its HELIOS system on a drone target, according to a recently released report.

We report on versatile orbital angular momentum beam generation through the association of a 61-channels coherent beam combining digital laser and a liquid-crystal q-plate. Particularly, high-order ...

The orbital angular momentum (OAM) carried by the vortex beams is considered as a new set forming the basis of carrier signals that is different from amplitude, phase, polarization, and frequency.

The proposed diffractive deep neural network employs orbital angular momentum encoding and diffractive layers to process spatial information from handwritten digits, offering a robust and ...

New technique accomplishes efficient recognition and real-time control of angular momentum modes. Rotating objects carry angular momentum; this fact extends even to the tiniest of particles, such as ...
