Quark Orbital Angular Momentum

EPJ Web of Conferences, 2015
Definitions of orbital angular momentum based on Wigner distributions are used as a framework to discuss the connection between the Ji definition of the quark orbital angular momentum and that of Jaffe and Manohar.

Angular and Orbital Angular Momenta in the Tight Focus of a Circularly Polarized Optical Vortex

Photonics, 2023
Based on the Richards-Wolf (RW) formalism, we obtain two different exact expressions for the angular momentum (AM) density of light in the focus of an optical vortex with a topological charge n and right circular polarization.

Large Angular Momentum

Magnetism
The quantum states of a spin 12 (a qubit) are parametrized by the space CP1∼S2, the Bloch sphere. A spin j for a generic j (a 2j+1-state system) is represented instead by a point in a larger space, CP2j.

Spin-constrained orbital-angular-momentum control in high-harmonic generation

Physical Review Research, 2019
The interplay between spin and orbital angular momentum in the up-conversion process allows us to control the macroscopic wave front of high harmonics by manipulating the microscopic polarizations of the driving field.

The Angular Momentum Unloading of the Asymmetric GEO Satellite by Using Electric Propulsion with a Mechanical Arm

Aerospace
A high-precision attitude control satellite uses an angular momentum exchange device such as a flywheel or a control moment gyro as the actuator for attitude stability control.

Global angular momentum generation in heavy-ion reactions within a hadronic transport approach [PDF]

EPJ Web of Conferences
In this study, we utilize the SMASH transport model to explore the generation of global angular momentum in heavy-ion collisions. Our results corroborate previous models, highlighting a pronounced peak in angular momentum transfer during mid-central ...

Dual electromagnetism: helicity, spin, momentum and angular momentum

New Journal of Physics, 2013
The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity and, as we show here, is closely related to the separation of spin ...

Angular momentum and chaos bound of charged particles around Einstein–Euler–Heisenberg AdS black holes

New Journal of Physics, 2022
In this paper, we investigate influences of the charge and angular momentum of a particle around a charged Einstein–Euler–Heisenberg AdS black hole on a Lyapunov exponent, and find spatial regions where the chaos bound is violated.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
