Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Non-Hermitian topological systems exhibit a range of unique phenomena that are absent in their Hermitian counterparts.

If you’ve ever really looked at how flamingos eat, you know how captivatingly peculiar it is. They bob their inverted heads in the water and do a kind of waddle cha-cha as they inch their way ...

The breakthrough experiments revealed that the quantum vortex is created by orbital angular momentum – electrons’ circular motion around atomic nuclei. “When we first saw signs that the predicted ...

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. The ...

A novel radar imaging technique based on orbital angular momentum (OAM) modulation is presented. First, the generation of electromagnetic (EM) vortex wave, which carries the OAM, using incrementally ...

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, ...

A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

Optical vortex plays an important role in a variety of fields, such as particle tweezing, quantum communication, astrophysics, and microscopy. Especially, the application of optical vortex has ...

That means the beam carries a rotational oomph known as orbital angular momentum. “This is something really very strange, very nonintuitive,” says physicist Edvardas Narevicius of the Weizmann ...

The new concept is based on unified transmission and detection of photons in a three-dimensional space of orbital angular momentum, entanglement, and hyperspectral characteristics.
