Abstract: Orbital angular momentum (OAM) of electromagnetic waves is a field with a short history of less than thirty years. Recent advances in modern technology have paved the way for the development ...

Abstract: We report the production of electron vortex beams carrying large orbital angular momentum (OAM) using micro-fabricated spiral zone plates. A series of the spherical waves, focussing onto ...

Furthermore, the total (spin and orbital) angular momentum Jtot of the stellar planetary system is computed, and a power law of the form J tot = 10 (43.11±6.82) ( M p M J ) (0.94±0.14) is obtained. In ...

Although the orbits are tight, they are still much larger than the electron orbitals in atoms—the perfect recipe for getting them to notice light carrying orbital angular momentum. The ...

The basic idea is to utilize not only an electron's charge, but also its spin and orbital moment when processing information. Spin is the intrinsic angular momentum of an electron, and the orbital ...

In the past few years, the interactions between spin angular momentum and orbital angular momentum in tightly focused structured light have attracted much attention. Different from the independent ...
