Quark Orbital Angular Momentum [PDF]
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.

Generation and Manipulation of Optical Ferris Wheel by Nested Spiral-Array Plates
IEEE Photonics Journal, 2022 Orbital angular momentum of light has attracted great attention in recent years. Optical ferris wheel, composed of the superposition of different orbital-angular-momentum modes, further broadens the application of orbital angular momentum of light in ...

Measurement of the orbital angular momentum of an astigmatic Hermite–Gaussian beam [PDF]
Компьютерная оптика, 2019 Here we study three different types of astigmatic Gaussian beams, whose complex amplitude in the Fresnel diffraction zone is described by the complex argument Hermite polynomial of the order (n, 0).

Photonic integrated chip enabling orbital angular momentum multiplexing for quantum communication
Nanophotonics, 2021 Light carrying orbital angular momentum constitutes an important resource for both classical and quantum information technologies. Its inherently unbounded nature can be exploited to generate high-dimensional quantum states or for channel multiplexing in

Orbital angular momentum: origins, behavior and applications [PDF]
, 2011 As they travel through space, some light beams rotate. Such light beams have angular momentum. There are two particularly important ways in which a light beam can rotate: if every polarization vector rotates, the light has spin; if the phase structure ...

Angular stripe phase in spin-orbital-angular-momentum coupled Bose condensates [PDF]
, 2020 We propose that a superfluid with supersolidlike properties, i.e., angular stripe phase, can be realized in a pancakelike spin-1/2 Bose gas with spin-orbital-angular-momentum coupling.

Orbital angular momentum in the nucleon [PDF]
Physical Review C, 2010 Analysis of the measured value of the integrated \bar{d}-\bar{u} asymmetry (Ifas = 0.147+-0.027) in the nucleon show it to arise from nucleon fluctuations into baryon plus pion. Requiring angular momentum conservation in these fluctuations shows the associated orbital angular momentum is equal to the value of the flavor asymmetry.
