The role of quantum computing in advancing plasma physics simulations for fusion energy and high-energy

open access: yesFrontiers in Physics
Its complexity constrains advancements in fusion energy and high energy applications driven by plasma physics, multiscale phenomena beyond classical computing limits. These transformative solutions, especially in plasma simulations, for which exponential

Global MHD Simulations: Magnetosphere–Ionosphere Coupling Dependence on Conductance Model

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Eighty‐five geomagnetic storms were simulated with the space weather modeling framework Geospace model using two different ionospheric conductance models. One set used the legacy conductances within the Ridley ionosphere model, while the other set used the newly developed conductance model for extreme events conductance model.

Solar Eruptions Triggered by Flux Emergence below or near a Coronal Flux Rope

open access: yesThe Astrophysical Journal
Observations have shown a clear association of filament/prominence eruptions with the emergence of magnetic flux in or near filament channels. Magnetohydrodynamic (MHD) simulations have been employed to systematically study the conditions under which ...

Impact of Induced Electric Fields Inside the Magnetopause on Magnetopause Shadowing of Radiation Belt Electrons

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Loss of relativistic electrons with energies above 0.5 MeV through the magnetopause, commonly referred to as magnetopause shadowing, has been extensively investigated using both simulations and observations. However, direct and systematic observational evidence remains limited. In this study, we extend a previously developed magnetopause model

The Importance of Ambipolar Heating in the Standard Thin Accretion Disk with Outflows

open access: yesThe Astrophysical Journal
This study examines the importance of the thermal effects of ambipolar diffusion (AD), by analyzing the governing properties in the middle and outer regions of a standard thin accretion disk with outflows.

Driving Dynamical Inner‐Heliosphere Models With In Situ Solar Wind Observations

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Accurately reconstructing the solar wind throughout the inner heliosphere is essential for understanding solar–terrestrial interactions and improving space‐weather forecasts. Conventional reconstruction methods rely on photospheric magnetic field observations and coronal models to estimate solar wind conditions near the Sun, typically at 0.1 ...

Research into the Magnetic Configuration of Eruptive Filaments with a High-class Flare

open access: yesThe Astrophysical Journal
Filament eruptions are the source of coronal mass ejections, and these phenomena are likely to pose a serious threat to space weather safety. The magnetic structures that carry the filament material are considered the core structures of the eruption, and

Self-similar Cosmic-Ray Transport in High-resolution Magnetohydrodynamic Turbulence

open access: yesThe Astrophysical Journal Letters
We study the propagation of cosmic rays (CRs) through a simulation of magnetohydrodynamic (MHD) turbulence at an unprecedented resolution of 10,240 ^3 . We drive turbulence that is subsonic and super-Alfvénic, characterized by δB _rms / B _0  = 2.

Simulation of β-induced Alfvén eigenmode instabilities and mode transition for HL-3 hybrid scenario

open access: yesNuclear Fusion
A kinetic-magnetohydrodynamic hybrid simulation is performed to investigate the Alfvén eigenmode (AE) and fishbone (FB)/FB-like (FBL) instabilities excited by neutral beam injection (NBI)-deposited energetic particles (EPs) in an HL-3 hybrid scenario ...
