Dressed soliton in quantum dusty pair-ion plasma
Nonlinear propagation of a quantum ion-acoustic dressed soliton is studied in a dusty pair-ion plasma. The Korteweg–de Vries (KdV) equation is derived using reductive perturbation technique. A h...

The anomalous transport of energetic ions in the presence of turbulent fields is investigated. Nonlinear simulations of a steady-state ITER [R. Aymar et al., Nucl. Fusion 41, 1301 (2001)] scenario have been carried out using the gyrokinetic turbulence code GENE [F. Jenko et al., Phys. Plasmas 7, 1904 (2000)], modeling the suprathermal particles as high temperature Maxwellian distributions in the passive tracer limit. Velocity space analysis shows that single particle diffusivities of ions above the critical energy are significantly larger than their neoclassical counterpart. ©2009 American Institute of Physics
