Quantum multiplexing with the orbital angular momentum of light [PDF]
Physical Review A, 2008 The orbital angular momentum, OAM, of photons offers a suitable support to carry the quantum data of multiple users. We present two novel optical setups that send the information of n quantum communication parties through the same free-space optical link.

Polarization-controlled evolution of light transverse modes and associated Pancharatnam geometric phase in orbital angular momentum [PDF]
, 2010 We present an easy, efficient and fast method to generate arbitrary linear combinations of light orbital angular momentum eigenstates $\ell=\pm 2$ starting from a linearly polarized TEM$_{00}$ laser beam.

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.

Nature Communications, 2020 Orbital angular momentum takes several forms in structured light beams. Here, the authors demonstrate control of dynamic spatiotemporal beams combining two forms of orbital angular momenta, by coherently adding frequency comb lines.

Conversion of twisted light to twisted excitons using carbon nanotubes
npj Computational Materials, 2022 Carbon nanotubes are explored as a means of coherently converting the orbital angular momentum of light to an excitonic form that is more amenable to quantum information processing. An analytical analysis, based on dynamical conductivity, is used to show

Spin-to-Orbital Angular Momentum Mapping of Polychromatic Light [PDF]
Physical Review Letters, 2018 Reflective geometric phase flat optics made from chiral anisotropic media recently unveiled a promising route towards polychromatic beam shaping. However, these broadband benefits are strongly mitigated by the fact that flipping the incident helicity does not ensure geometric phase reversal.

Acoustic orbital angular momentum Hall effect and realization using a metasurface
Physical Review Research, 2021 Vortex beams with a twisted wavefront possess both intrinsic and extrinsic orbital angular momenta. Their coupling (viz. orbital-orbital coupling) leads to an orbital angular momentum Hall effect previously found in light, providing applications in light

Efficient Sorting of Orbital Angular Momentum States of Light
Physical Review Letters, 2010 We present a method to efficiently sort orbital angular momentum (OAM) states of light using two static optical elements. The optical elements perform a Cartesian to log-polar coordinate transformation, converting the helically phased light beam corresponding to OAM states into a beam with a transverse phase gradient.

Carrying Data on the Orbital Angular Momentum of Light [PDF]
IEEE Communications Magazine, 2018 The use of fiber optic cable in support of bandwidth expansion has become de rigeur. Not only does optical fiber offer tremendous bandwidth, it is also low in attenuation, small in cross section, inexpensive, and impervious to electromagnetic interference, and there are significant economies of scale on components developed for the myriad of optical ...

Partonic angular momentum in the nucleon's chiral periphery
Physics Letters B, 2019 We study the nucleon's partonic angular momentum (AM) content at peripheral transverse distances b=O(Mπ−1), where the structure is governed by chiral dynamics.
