TL;DR: In this paper, the authors compared the performance of gyrokinetic and gyrofluid simulations of ion-temperature gradient (ITG)instability and turbulence in tokamak plasmas as well as some tokak plasma thermal transportmodels.

TL;DR: In this article, a large-scale simulation of ion temperature gradient-driven turbulence was performed using a toroidal electrostatic gyrokinetic particle-in-cell simulation model, including global equilibrium effects.

TL;DR: In this paper, it was shown that the terahertz conductivity of a structurally confined Drude gas of electrons is actually suppressed at low frequencies due to carrier confinement on the diffusion length scale and not due to backscattering.

TL;DR: In this article, the authors measured the radial correlation length of the turbulence Lc,r is shown to scale with the local ion gyroradius, Lc r ≈ 5ρi, while the decorrelation times scale with local acoustic velocity as τ c~a/cs.

TL;DR: In this paper, the authors present coordinated ground satellite observations of solar wind compression-related dayside electromagnetic ion cyclotron (EMIC) waves from 25 September 2005, which suggest that generation of the EMIC waves and consequent loss of energetic protons may last for several hours while the magnetosphere remains compressed.
