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 ...

Spin angular momentum modulation via spin–orbit interaction in fractional orbital angular momentum beams [PDF]
NanophotonicsLight exhibits both spin and orbital angular momentum (SAM and OAM). These two forms of angular momentum remain independent in paraxial fields, but become coupled in confined fields through spin–orbit interactions (SOI).

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.

Visualizing a single wavefront dislocation induced by orbital angular momentum in graphene [PDF]
Nature CommunicationsPhase singularities are phase-indeterminate points where wave amplitudes are zero, which manifest as phase vertices or wavefront dislocations. In the realm of optical and electron beams, the phase singularity has been extensively explored, demonstrating ...

Spin and orbital angular momentum of coherent photons in a waveguide
Frontiers in Physics, 2023 Spin angular momentum of a photon corresponds to a polarisation degree of freedom of lights, and such that various polarisation properties are coming from macroscopic manifestation of quantum-mechanical properties of lights.

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).
