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.
Physicists have used a machine-learning method to identify surprising new twists on the non-reciprocal forces governing a many-body system.

Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred to as "light dragging," is typically imperceptible when light is traveling in most widely available ...
Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, spinning cylinders to confirm that an uneven wobble in a ring of electrically conductive fluid like liquid ...
