Nonlinear gyrokinetic equations play a fundamental role in our understanding of the long-
time behavior of strongly magnetized plasmas. The foundations of modern nonlinear …

Dynamics of shear Alfvén waves and energetic particles are crucial to the performance of
burning fusion plasmas. This article reviews linear as well as nonlinear physics of shear …

Superthermal energetic particles (EP) often drive shear Alfvén waves unstable in
magnetically confined plasmas. These instabilities constitute a fascinating nonlinear system …

Since the last IAEA Fusion Energy Conference in 2018, significant progress of the
experimental program of HL-2A has been achieved on developing advanced plasma …

A general theoretical framework for investigating the nonlinear dynamics of phase space
zonal structures is presented in this work. It is then, more specifically, applied to the limit …

Geodesic acoustic modes (GAM) are shown to constitute a continuous spectrum due to
radial inhomogeneities. The importance and theoretical as well as experimental implications …

This paper describes advances made in the field of energetic-particle physics since the
topical review of Alfvén eigenmode observations in toroidal plasmas (Wong 1999 Plasma …

We present an overview on one issue of practical interest for burning plasmas, ie whether
fast ions and charged fusion products are sufficiently well confined such that they transfer …

The theoretical framework of the general fishbone-like dispersion relation (GFLDR),
presented and discussed in the Companion Paper [Phys. Plasmas 21, 072120 (2014)], is …

The excitation of collective instabilities by super-thermal particles in hot plasmas and the
related transport processes attract increasing interest due to their fundamental challenges …
