Plasma physics is the research area devoted to the theoretical, computational, and experimental study of ionized gases in which collective electromagnetic interactions dominate particle dynamics. It encompasses fundamental processes such as Debye shielding, plasma oscillations, waves and instabilities, magnetohydrodynamics, kinetic phenomena described by the Vlasov and Boltzmann equations, and nonlinear structures like solitons and turbulence. The field underpins research in controlled thermonuclear fusion (e.g., tokamaks, stellarators, inertial confinement), space and astrophysical plasmas (solar wind, magnetospheres, accretion disks), and high-energy-density physics, and it relies heavily on advanced diagnostics, numerical simulations, and multi-scale modeling of charged-particle behavior.
Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses. Drawing on more than ...

When a gas is highly energized, its electrons get torn from the parent atoms, resulting in a plasma—the oft-forgotten fourth state of matter (along with solid, liquid, and gas). When we think of plasmas, we normally think ...
