Super-resolution orbital angular momentum holography
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.

Orbital-angular-momentum entanglement in turbulence [PDF]
Physical Review A, 2013 The turbulence induced decay of orbital angular momentum (OAM) entanglement between two photons is investigated numerically and experimentally. To compare our results with previous work, we simulate the turbulent atmosphere with a single phase screen based on the Kolmogorov theory of turbulence.

Probing Molecular Chirality by Orbital-Angular-Momentum-Carrying X‑ray Pulses [PDF]
, 2019 A twisted X-ray beam with orbital angular momentum is employed in a theoretical study to probe molecular chirality. A nonlocal response description of the matter-field coupling is adopted to account for the field short wavelength and the structured ...

Self-homodyne detection of the light orbital angular momentum [PDF]
, 2012 A simple optical system for the self-homodyne detection of the orbital angular momentum (OAM) carried by optical beams is introduced. We propose two different schemes based on the use of optical hybrids, which could detect the OAM mode number, even ...

Rotation of electromagnetic fields and the nature of optical angular momentum [PDF]
, 2010 The association of spin and orbital angular momenta of light with its polarization and helical phase fronts is now well established. The problems in linking this with electromagnetic theory, as expressed in Maxwell's equations, are rather less well known.

Spin-orbit interaction of light induced by transverse spin angular momentum engineering
Nature Communications, 2018 Harnessing both orbital and spin angular momentum in light fields enables various applications in bio-sensing and nano-photonics. Here, the authors create engineered spin-orbit coupling between orbital angular momentum and transverse spin angular ...

Nested SU(2) symmetry of photonic orbital angular momentum
Frontiers in Physics, 2023 The polarization state is described by a quantum mechanical two-level system, which is known as special unitary group of degree 2 [SU(2)]. Polarization is attributed to an internal spin degree of freedom inherent to photons, while photons also possess an
