Super-resolution orbital angular momentum holography [PDF]
Nature Communications, 2023 The resolution of orbital angular momentum holography is limited by a fundamental sampling criterion. Here, the authors break the resolution barrier by temporal multiplexing of binary holograms and enhance the resolution and capacity by several times.

Entanglement of the orbital angular momentum states of photons [PDF]
Nature, 2001 So far experimental confirmation of entanglement has been restricted to qubits, i.e. two-state quantum systems including recent realization of three- and four-qubit entanglements. Yet, an ever increasing body of theoretical work calls for entanglement in quantum system of higher dimensions.

Metasurface orbital angular momentum holography [PDF]
Nature Communications, 2019 Conventional hologram designs lack orbital angular momentum selectivity. Here, the authors design metasurface holograms consisting of GaN nanopillars with discrete spatial frequency distributions allowing the reconstruction of distinctive orbital angular

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.

Gravitational waves with orbital angular momentum [PDF]
European Physical Journal C: Particles and Fields, 2020 Compact orbiting binaries like the black hole binary system observed in GW150914 carry large amount of orbital angular momentum. The post-ringdown compact object formed after merger of such a binary configuration has only spin angular momentum, and this ...

QUARK ORBITAL ANGULAR MOMENTUM IN THE BARYON [PDF]
International Journal of Modern Physics A, 2001 Analytical and numerical results, for the orbital and spin content carried by different quark flavors in the baryons, are given in the chiral quark model with symmetry breaking. The reduction of the quark spin, due to the spin dilution in the chiral splitting processes, is transferred into the orbital motion of quarks and antiquarks.

Time-domain observation of ballistic orbital-angular-momentum currents with giant relaxation length in tungsten. [PDF]
Nat Nanotechnol, 2023 The emerging field of orbitronics exploits the electron orbital momentum L. Compared to spin-polarized electrons, L may allow the transfer of magnetic information with considerably higher density over longer distances in more materials.

Structured transverse orbital angular momentum probed by a levitated optomechanical sensor. [PDF]
Nat Commun, 2023 The momentum carried by structured light fields exhibits a rich array of surprising features. In this work, we generate transverse orbital angular momentum (TOAM) in the interference field of two parallel and counter-propagating linearly-polarised ...

Achromatic orbital angular momentum generator [PDF]
New Journal of Physics, 2014 We describe a novel approach for generating light beams that carry orbital angular momentum (OAM) by means of total internal reflection in an isotropic medium.

Topologically trivial graphene enables mid-infrared orbital angular momentum detection toward on-chip integration [PDF]
Light: Science & ApplicationsA mid-infrared orbital angular momentum detector based on multilayer graphene has been successfully developed, overcoming the previous reliance on C2V point group topological Weyl semimetals via the orbital photogalvanic effect.
