Fractional OAM charge ℓ=1.5 induces an optimal 67.5° GKP lattice rotation that reduces error rate 23.9× with <0.2% loss in Fisher information and yields 41% higher metrological capacity.
LG modes with radial index p > 8 suppress the unstable n = |ℓ| Zernike components, remaining more robust in turbulence; receiver diameter scales as 2 w0 √(2p + |ℓ| + 3).
In the small-trap limit, overdamped colloidal particles on a driven periodic path exhibit a sharp transition from zero to finite current above critical number n_c due to clustering of n_c particles.
Presents a plasmonic metasurface reflective q-plate that converts OAM to ultrashort pulses without temporal broadening across wide wavelengths.
Proposes a symmetry-protected quantum computing architecture that combines the generalized Kohn theorem, OAM light control, and metamaterial nanofocusing for any parabolic-confinement platform.
An overview of vortex solutions to the Helmholtz equation using an operator approach connected to the rotation group, with focus on paraxial OAM beam propagation.
