Two-loop turbulent helical magnetohydrodynamics: Large-scale dynamo and energy spectrum

Thu, 07/24/2025 - 10:00

Author(s): Michal Hnatič, Tomáš Lučivjanský, Lukáš Mižišin, Yurii Molotkov, and Andrei Ovsiannikov

We present a two-loop field-theoretic analysis of incompressible helical magnetohydrodynamics (MHD) in fully developed stationary turbulence. A key feature of helical MHD is the appearance of an infrared-unstable “masslike” term in the loop diagrams of the magnetic response function. Physically, thi…

Quantification of ion scattering by solar-wind current sheets: Pitch-angle diffusion rates

Wed, 07/23/2025 - 10:00

Author(s): Zijin Zhang, Anton V. Artemyev, and Vassilis Angelopoulos

The transport of energetic particles in the heliosphere is profoundly influenced by interactions with coherent structures in the turbulent magnetic field of the solar wind, particularly current sheets. While prior studies have largely relied on idealized turbulence models, this work quantifies the r…

Author(s): Masaru Nakanotani, Luis Lazcano Torres, Gary P. Zank, and Edward Thomas, Jr.

The Jeans instability in a magnetized dusty plasma is considered a fundamental process in space, where magnetic fields are common. We investigate the Jeans instability in a magnetized dusty plasma using 1D and 2D particle-in-cell simulations, in which dust grains are treated as particles and the Poi…

Author(s): T. A. Shelkovenko, I. N. Tilikin, A. R. Mingaleev, V. M. Romanova, and S. A. Pikuz

The small-sized, low-voltage, and low-inductive KING generator (190–230 kA, 40 kV, 200–240 ns) was specially designed to work with X-pinches; however, it was unstable in its original design. In the present work, it is experimentally shown that an increase in the inductance of the output node of the …

Author(s): Zekun Xu, Fuyuan Wu, Zhuang Zhao, Shigeo Kawata, and Jie Zhang

Magnetized fusion has been used in various inertial confinement fusion concepts to relax ignition requirements. Strong magnetic fields would induce burning asymmetry, which may be usually harmful to the central ignition schemes. However, it could be utilized in some intrinsically asymmetric ignition…

Effective theory for stochastic particle acceleration, with application to magnetized turbulence

Thu, 07/10/2025 - 10:00

Author(s): Martin Lemoine

Building on his previous work, the author develops an analytical theory for particle acceleration due to electric fields in magnetohydrodynamic turbulence. The theory, that is also valid in several nonturbulent cases – and captures nonresonant mechanisms such as Fermi and betatron acceleration, magnetic pumping, curvature drift, and transit-time damping – should be of high value in the area of astrophysics, in particular for the study of relativistic particle acceleration.
