| Zusammenfassung |
| A dispersive Landau-fluid model is used to study the decay and modulational
instabilities of circularly-polarized Alfvén waves in a collisionless
plasma, as well as their nonlinear developments. Comparisons are presented
with the drift-kinetic approximation for the dispersionless regime and with
hybrid simulations in more general conditions. The effect of the nature
of the instability on particle heating is discussed, together with the
formation of coherent structures or the development of an inverse cascade. |
