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

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

This study reveals how optical vortex beams influence ionization, offering new insights for technology in imaging, particle ...

The team hopes that the vortex-like behavior of electrons in momentum space could pave the way for new quantum technologies, such as orbitronics, which would use electrons’ orbital torque to transmit ...

In this letter, a spherical conformal antenna is designed, fabricated, and experimentally demonstrated to realize the beam steering of orbital angular momentum (OAM) vortex waves with hemisphere ...

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

In 1992, Allen and others discovered that light beams could carry quantized orbital angular momentum, laying the theoretical foundation for electron vortex technology. Electrons, as charged particles, ...

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.

We investigate the behavior of the orbital angular momentum (OAM) flux density of partially coherent vortex (PCV) beams in atmospheric turbulence. It is shown that for PCV beams with different spatial ...

Since the dynamic signature of vortex beams is determined by the OAM mode, the OAM mode measurement is one of the crucial tasks which is prior to the applications of vortex beams.
