Nonlinear phenomena in plasmas constitute a research area focused on collective behaviors that arise when plasma responses cannot be described by linearized fluid or kinetic equations. This includes the study of wave–wave and wave–particle interactions, parametric instabilities, turbulence, solitons, shocks, magnetic reconnection, and self-organization processes. Researchers investigate how nonlinearities in the Vlasov–Maxwell or magnetohydrodynamic (MHD) equations lead to energy transfer across scales, anomalous transport, and structure formation in laboratory, space, and astrophysical plasmas, using analytical theory, numerical simulations, and experiments to understand and control these complex dynamical regimes.
How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter timescales. In a study published ...

One particularly well-known fact about the moon is that it doesn't have much of a magnetosphere to speak of. There's no blanket to protect it from the solar wind ravaging its surface, blowing away its atmosphere and charging ...

In a new study published in Physical Review Letters, scientists have performed the first global simulations of monster shocks—some of the strongest shocks in the universe—revealing how these extreme events in magnetar magnetospheres ...
Measuring conditions in volatile clouds of superheated gases known as plasmas is central to pursuing greater scientific understanding of how stars, nuclear detonations and fusion energy work. For decades, scientists have ...
