Low-frequency, parallel propagating AlfvÃ©nic turbulence in collisionless plasmas is theoretically studied. AlfvÃ©nic turbulence is derived as an equilibrium state (Beltrami field) in the magnetohydrodynamic equations with the pressure anisotropy and multi-species of ions. It is shown that...

A simple large-aspect-ratio (R0/r) circular equilibrium model is developed for low-beta reversed field pinch (RFP) geometry. The model is suitable for treating small scale instability and turbulent transport driven by ion temperature gradient (ITG) and related electron drift modes in gyrokinetic...

Anomalous heat transport due to ion-temperature-gradient- (ITG)-driven turbulence is studied with the use of a low-degree-of-freedom model composed of 18 ordinary differential equations (ODEs). When the system is slightly above the stability threshold of ITG mode, the system is in the convection...

The excitation of stable eigenmodes in unstable plasma turbulence, previously documented in collisionless trapped electron mode turbulence, is shown to be a generic behavior of local (quasihomogeneous) systems. A condition is derived to indicate when such excited eigenmodes achieve a sufficient...

The implementation of linearized operators describing inter- and like-species collisions in the global gyrokinetic particle-in-cell code ORB5 [S. Jolliet, Comput. Phys. Commun. 177, 409 (2007)] is presented. A neoclassical axisymmetric equilibrium with self-consistent electric field can be...

In Langevin-Dynamics simulations of large aggregates of up to 106 dust grains we study the continuous transition from a liquid-like to a solid state. In this freezing two-dimensional Yukawa liquid the hexagonal solid phase cascades to larger scales by domain merging, while defects pile up on the...

Zonal flow helps reduce and regulate the turbulent transport level in tokamaks. Rosenbluth and Hinton have shown that zonal flow damps to a nonvanishing residual level in collisionless [M. Rosenbluth and F. Hinton, Phys. Rev. Lett. 80, 724 (1998)] and collisional [F. Hinton and M. Rosenbluth,...

The collisionless limit of the transition to ion-temperature-gradient-driven plasma turbulence is considered with a dynamical-systems approach. The importance of systematic analysis for understanding the differences in the bifurcations and dynamics of linearly damped and undamped systems is...
