Orbital Angular Momentum for Wireless Communications [PDF]
IEEE Wireless Communications, 2019 As the traditional resources (frequency, time, space, etc.) are efficiently utilized, it becomes more and more challenging to satisfy the ever-lasting capacity-growing and users-boosting demand in wireless networks. Recently, the electromagnetic (EM) wave was found to possess not only linear momentum, but also angular momentum.

Quark angular momentum in a spectator model
Physics Letters B, 2015 We investigate the quark angular momentum in a model with the nucleon being a quark and a spectator. Both scalar and axial-vector spectators are included.

Acoustic orbital angular momentum transfer to matter by chiral scattering
New Journal of Physics, 2015 We report on orbital angular momentum exchange between sound and matter mediated by a non-dissipative chiral scattering process. An experimental demonstration is made possible by irradiating a three-dimensional printed, spiral-shaped chiral object with ...

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe
Advanced Functional Materials, EarlyView.By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Orbital angular momentum at small x [PDF]
Journal of High Energy Physics, 2019 AbstractWe determine the small Bjorkenxasymptotics of the quark and gluon orbital angular momentum (OAM) distributions in the proton in the double-logarithmic approximation (DLA), which resums powers ofαsln2(1/x) withαsthe strong coupling constant. Starting with the operator definitions for the quark and gluon OAM, we simplify them at smallx, relating ...

Study of the propagation and detection of the orbital angular momentum of light for astrophysical applications [PDF]
, 2013 The aim of this work is to study the propagation of orbital angular momentum (OAM) of light for astrophysical applications and a method for OAM detection with optical telescopes. The thesis deals with the study of the orbital angular momentum (OAM) as a

Exchange‐Coupled Two‐Dimensional MOFs
Advanced Functional Materials, EarlyView.Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.

Orbital angular momentum of the spiral beams [PDF]
Компьютерная оптика, 2019 At first sight, any rotation generates some angular momentum (it is true for a solid body). But these characteristics (rotation and orbital angular momentum) are rather different for optics and mechanics.
