Effects of plasma turbulence on the nonlinear evolution of magnetic island in tokamak [PDF]
Nature Communications, 2021 Magnetic reconnection and plasma turbulence occur in atmospheric and magnetized laboratory plasmas. Here the authors report evolution of magnetic islands and plasma turbulence in tokamak plasmas using high resolution 2D electron cyclotron emission ...

Review of plasma turbulence experiments. [PDF]
Proc Jpn Acad Ser B Phys Biol Sci, 2021 Understandings of turbulent plasma have been developed along with nuclear fusion research for more than a half century. Long international research has produced discoveries concerning turbulent plasma that allow us to notice the hidden nature and physics questions that could contribute to other scientific fields and the development of technologies ...

Fluidization of collisionless plasma turbulence. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance Two textbook physical processes compete to thermalize turbulent fluctuations in collisionless plasmas: Kolmogorov’s “cascade” to small spatial scales, where dissipation occurs, and Landau’s damping, which transfers energy to small scales in velocity space via “phase mixing,” also leading to dissipation.

Statistical theory of plasma turbulence [PDF]
Plasma and Fusion Research, 2009 We present a statistical theory of intermittency in plasma turbulence based on short-lived coherent structures (instantons). In general, the probability density functions (PDFs) of the flux R are shown to have an exponential scaling P(R) ∝ exp (-cRs ) in

Advanced analysis of spatiotemporal behaviors of modal structures and couplings for plasma tomography [PDF]
Scientific ReportsAdvanced methods, based on the Fourier-Rectangular Function (FRF) series expansion (K. Yamasaki et al., J.Appl. Phys. 126 043304 (2019)), are proposed to analyse plasma images obtained with tomography.

The Astrophysical Journal, 2023 Nearly incompressible magnetohydrodynamic (NI MHD) theory for β ∼ 1 (or β ≪ 1) plasma has been developed and applied to the study of solar wind turbulence. The leading-order term in β ∼ 1 or β ≪ 1 plasma describes the majority of 2D turbulence, while the
