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.

Supersonic plasma turbulence in the laboratory. [PDF]
Nat Commun, 2019 AbstractThe properties of supersonic, compressible plasma turbulence determine the behavior of many terrestrial and astrophysical systems. In the interstellar medium and molecular clouds, compressible turbulence plays a vital role in star formation and the evolution of our galaxy.

Fluid Turbulence in Quantum Plasmas [PDF]
Physical Review Letters, 2007 Nonlinear fluid simulations are developed by us to investigate the properties of fully developed two-dimensional (2D) electron fluid turbulence in a very dense Fermi (quantum) plasma. We find that a 2D quantum electron plasma exhibits dual cascades, in which the electron number density cascades towards smaller turbulent scales, while the electrostatic ...
