Drift waves occur universally in magnetized plasmas producing the dominant mechanism for
the transport of particles, energy and momentum across magnetic field lines. A wealth of …

This overview is an assessment of the gyrokinetic framework and simulations to compute
turbulent transport in fusion plasmas. It covers an introduction to the gyrokinetic theory, the …

Guiding-center theory provides the reduced dynamical equations for the motion of charged
particles in slowly varying electromagnetic fields, when the fields have weak variations over …

Recent nonlinear gyrokinetic simulations have shown that hyperfine-scale turbulence at
perpendicular spatial scales comparable to or smaller than the ion gyroradius driven by …

This paper addresses non-linear gyrokinetic simulations of ion temperature gradient (ITG)
turbulence in tokamak plasmas. The electrostatic GYSELA code is one of the few …

Global electrostatic ITG turbulence physics, together with background dynamics, has been
simulated in a realistic tokamak core geometry using XGC1, a full-function 5D gyrokinetic …

Velocity–space structures of ion distribution function associated with the ion temperature
gradient (ITG) turbulence and the collisionless damping of the zonal flow are investigated by …

A set of nonlinear gyrofluid equations for simulations of tokamak turbulence are derived by
taking moments of the nonlinear toroidal gyrokinetic equation. The moment hierarchy is …

Energy and particle confinement in tokamaks is usually anomalous, greatly exceeding
neoclassical predictions. It is desirable to develop an understanding of the underlying …

A global gyrokinetic toroidal full-f five-dimensional Vlasov simulation GT5D (Idomura et al
2008 Comput. Phys. Commun. 179 391) is extended including sources and collisions. Long …
