This session focuses on the non-linear processes taking place in space, laboratory, and astrophysical plasmas. In many cases, these processes appear deeply linked. For instance, magnetic reconnection is an established ingredient of the turbulence cascade, and it is also responsible for the production of turbulence in reconnection outflows and for the onset of a number of instabilities especially at the depolarization fronts. Turbulent dynamos are expected to play a role in the generation and growth of magnetic fields in a number of astrophysical and heliospheric settings. Shocks can result in turbulence formation, for example, in the turbulent magnetosheath, and can be efficient particle accelerators.

The study of these processes has seen significant progress in recent years thanks to a synergistic approach based on simulations and observations. On the one hand, simulations can deliver output on a range of temporal and spatial range of scales, going from fluid to electron kinetic scales. This is partly also due to the advent of GPU facilities, which have significantly increased the capability of numerical simulations in plasma physics. On the other hand, high cadence spacecraft measurements of particles and fields and high-resolution 3D measurements of particle distribution functions are currently provided by missions such as MMS, Parker Solar Probe, and Solar Orbiter. These missions are opening new research scenarios in heliophysics and providing a consistent amount of new data to be analysed. Furthermore, other present and future missions that will give unique plasma measurements around solar system magnetospheres, such as Bepi Colombo, Juice, Comet Interceptor, Plasma Observatory and HelioSwarm, are demanding the development of new numerical tools for successful interpretation of the observations.

This session welcomes simulation, observational, and theoretical contributions relevant to studying the above-mentioned processes. We also encourage papers proposing new methods in simulation techniques and data analysis, for example, those rooted in Artificial Intelligence or those based on multi-point satellite observations.
