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

Central to recent advances is the manipulation of the electron’s orbital angular momentum (OAM), which arises from a helical phase structure in the electron’s wave function.

Unlike the standard view of dark matter as a cloud of heavy, sluggish particles with no internal structure, the new research focuses ... that these vortex lines are aligned with the total angular ...

From living matter to molecules to elementary particles, the world is made of “chiral” objects that differ from their ...

Optical vortex is a structured beam with a spiral phase wavefront. Different orbital angular momentums (OAM) are orthogonal to each other and multiplexed together without crosstalk. Vortex optical ...

There is a growing interest in structured light, especially orbital angular momentum (OAM) beams, due to its unique amplitude and phase structure. Multiple orthogonal OAM beams can be utilized to ...

The usual use of this demonstration will be to introduce the concept of angular momentum and motion in non-inertial frames, so it is simplest to use the R/Theta formulation. The F=ma equation can be ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...
