Phase-Space Energy Transfer of Wave-Particle Interactions using the Field-Particle Correlation Technique and Linear Plasma Theory with JET-PLUME
Collin R. Brown, Gregory G. Howes, Kristopher G. Klein +1
The collisionless transfer of energy between fields and particles through wave-particle interactions is a fundamental process in space plasmas but remains incompletely characterize…
Plasma Instabilities in Arbitrary Distributions: Comparison between ALPS and BO
Xudong Guo, Huasheng Xie, Kristopher G. Klein +3
Determining accurate wave dispersion relations is a central problem in plasma physics. Recent advances have enabled the numerical computation of linear dispersion relation in plasm…
Wave-particle equilibria with heavy ions in weakly collisional space plasmas
Nicolás Villarroel-Sepúlveda, Daniel Verscharen, Pablo S. Moya +2
Space plasmas are weakly collisional since characteristic time scales related to Coulomb collisions are much larger than those of Larmor gyration or wave--particle interactions. Th…
Velocity-Space Signatures of Energy Transfer for Ion-Acoustic Instabilities
Mahmoud Saad Afify, Kristopher G. Klein, Mihailo M. MartinoviÄ +1
Context. Observations by Parker Solar Probe (PSP) of electrostatic waves suggest that electrostatic instabilities, including the ion-ion-acoustic instability (IIAI) frequently obse…
The Dielectric Response of Plasmas with Arbitrary Gyrotropic Velocity Distributions
Kristopher Klein, Daniel Verscharen
Hot and tenuous plasmas are frequently far from local thermodynamic equilibrium, necessitating sophisticated methods for determining the associated plasma dielectric tensor and nor…
