Density of optical degrees of freedom : intensity, linear and angular momentum [PDF]

, 2014
For any optical system, optical eigenmodes describe solutions of Maxwells equations that are orthogonal to each other. In their simplest free space form, these modes correspond, for example, to Bessel, Laguerre-Gaussian or Hermite-Gaussian beams. However,

On the dragging of light by a rotating medium [PDF]

, 2007
When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

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.

Generation and manipulation of laser beams carrying orbital angular momentum for classical and quantum information applications [PDF]

, 2009
Light orbital angular momentum (OAM) has been recognized as a new promising resource for classical and quantum information applications. In contrast to the spin angular momentum, the OAM is an inherently multidimensional.

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 ...

Polarization and image rotation induced by a rotating dielectric rod: an optical angular momentum interpretation [PDF]

, 2006
When light is transmitted along the axis of a rotating glass rod, the polarization of the light is rotated through a small angle [Proc. R. Soc. London, Ser. A349, 423 (1976)].

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 ...

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 ...
