Standing electron acoustic waves (EAWs) are observed in a pure ion plasma. EAWs are
slow nonlinear plasma waves; at small amplitude their phase velocities (⁠ v ph≃ 1.4 v for …

A theoretical framework has been developed for an NBI scenario to model the hard non-
linear evolution of global Alfvén eigenmodes (GAEs) where the adiabatic motion of phase …

Long range frequency sweeping events are simulated numerically within a one-
dimensional, electrostatic bump-on-tail model with fast particle sources and collisions. The …

Long range frequency chirping of Bernstein–Greene–Kruskal modes, whose existence is
determined by the fast particles, is investigated in cases where these particles do not move …

In a collisionless, unbounded, one-dimensional plasma, modelled using periodic boundary
conditions, formation of steady state phase space coherent structures or phase space …

In the presence of an energetic particle population in a dissipative plasma, self-trapped
structures in phase-space (holes and clumps) emerge from nonlinear wave-particle …

Frequency sweeping (chirping) of high frequency magnetohydrodynamic modes is widely
observed in tokamak plasmas. In this paper observations of chirping in neutral-beam-heated …

The evolution of chirp-driven electrostatic waves in unmagnetized plasmas is numerically
investigated by using a one-dimensional (1D) Vlasov-poisson solver with periodic boundary …

Interchange instabilities excited by energetic electrons trapped by a magnetic dipole
nonlinearly saturate and exhibit complex, coherent spectral characteristics and frequency …

The guiding centre dynamics of fast particles can alter the behaviour of energetic particle
(EP) driven modes with chirping frequencies. In this paper, the applicability of an earlier …
