The Simulation of Vortex Modes in Twisted Few-Mode Fiber With Inverse-Parabolic Index Profile
Published 2020-01-01“…These eigenstates correspond to orbital angular momentum modes except for the two polarized-vortex modes. The design of appropriate core parameters can lead to the difference in the effective refractive indexes between all adjacent modes being greater than 10<sup>−4</sup> over a bandwidth of 1.5 to 1.6 μm, which is expected to be an ideal method for the generation of multiple vortex modes in few-mode fiber for optical communication. …”

Impact of the Western Tibetan Vortex on Springtime Snow Cover Over the Western Tibetan Plateau
Published 2025-07-01“…This study finds that springtime snow cover variability over the western TP tail is significantly modulated by the Western Tibetan Vortex (WTV), which explains up to 40% variance. Cyclonic (anticyclonic) WTV variability generally causes water vapor convergence (divergence) and ascending (sinking) motions over the western TP tail, which thereby leads to more (less) snowfall and snow cover about one day later. …”

3D Magnetohydrodynamic Wave Propagation and Energy Transport in a Simulated Solar Vortex
Published 2025-01-01“…We attribute this increase to the dynamical pressure from the rotational flow increasing the plasma density at the tube boundary, which acts to trap the wave energy more effectively inside the vortex. Moreover, we demonstrate how the Poynting flux is always directed upward in weakly twisted magnetic flux tubes.…”
