Past rewinding of fluid dynamics from noisy observation via physics-informed neural computing

J Seo - Physical Review E, 2024 - APS
Reconstructing the past of observed fluids has been known as an ill-posed problem due to
both numerical and physical challenges, especially when observations are distorted by …

Core localized alpha-channeling via low frequency Alfven mode generation in reversed shear scenarios

S Wei, T Wang, L Chen, F Zonca, Z Qiu - Nuclear Fusion, 2022 - iopscience.iop.org
A novel channel for fuel ions heating in tokamak core plasma is proposed and analyzed
using nonlinear gyrokinetic theory. The channel is achieved via spontaneous decay of …

Measurement of zero-frequency fluctuations generated by coupling between Alfv\'en modes in the JET tokamak

JR Ruiz, J Garcia, M Barnes, M Dreval… - arXiv preprint arXiv …, 2024 - arxiv.org
We report the first experimental detection of a zero-frequency fluctuation that is pumped by
an Alfv\'en mode in a magnetically confined plasma. Core-localized bidirectional Alfv\'en …
