Energetic particles in plasmas are often the cause of interesting wave-particle interactions that fundamentally influence the stability of the plasma. In fusion plasmas enclosed by magnetic fields, for example, they can excite special forms of oscillation; the solar wind hitting the Earth's atmosphere can generate chorus waves. We are developing novel numerical methods to simulate such phenomena, combining efficient fluid models to describe the wave with more elaborate kinetic models to describe the particles.
