Orbital angular momentum and nonparaxial light beams
The simple relationship between total angular momentum and energy and the seemingly natural separation of the angular momentum into spin and orbital components in the paraxial approximation, are investigated for a general nonparaxial form of monochromatic beam with near cylindrical symmetry.
متن کاملSpin-to-orbital angular momentum conversion in dielectric metasurfaces: erratum.
We would like to clarify our paper [Opt. Express25, 377 (2017)] abstract sentence "These beams carry orbital angular momentum proportional to the number of intertwined helices constituting the wavefront."
متن کاملSpin and Orbital Angular Momentum Distribution Functions of the Nucleon
A theoretical prediction is given for the spin and orbital angular momentum distribution functions of the nucleon within the framework of an effective quark model of QCD, i.e. the chiral quark soliton model. An outstanding feature of the model is that it predicts fairly small quark spin fraction of the nucleon ∆Σ ≃ 0.35, which in turn dictates that the remaining 65% of the nucleon spin is carri...
متن کاملOrbital and Spin Angular Momentum of Electromagnetic Fields
1 Problem Poynting [1] identified the flux of energy in the electromagnetic fields {E, B} (in a medium with relative permittivity = 1 and relative permeability μ = 1) with the vector S = c 4π E × B, (1) in Gaussian units, where c is the speed of light in vacuum. Abraham [2] recognized the additional role of the Poynting vector as being proportional to the density of linear momentum stored in th...
متن کاملInterplay of spin and orbital angular momentum in the proton.
We derive the consequences of the Myhrer-Thomas explanation of the proton spin problem for the distribution of orbital angular momentum on the valence and sea quarks. After QCD evolution, these results are found to be in very good agreement with both recent lattice QCD calculations and the experimental constraints from Hermes and JLab.
