Effect of temperature anisotropy on the dynamics of geodesic acoustic modes
J. N. Sama, A. Biancalani, A. Bottino +7
In this work, we revisit the linear gyro-kinetic theory of geodesic acoustic modes (GAMs) and derive a general dispersion relation for an arbitrary equilibrium distribution functio…
Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
A pressure tensor description for the time-resonant Weibel instability
M. Sarrat, D. Del Sarto, A. Ghizzo
We discuss a fluid model with inclusion of the complete pressure tensor dynamics for the description of Weibel type instabilities in a counterstreaming beams configuration. Differe…
Kinetic Electrostatic Electron Nonlinear (KEEN) Waves and their Interactions Driven by the Ponderomotive Force of Crossing Laser Beams
Bedros Afeyan, K. Won, V. Savchenko +3
We have found, using 1D periodic Vlasov-Poisson simulations, new nonlinear, nonstationary, stable, long lived, coherent structures in phase space, called kinetic electrostatic elec…
