Practical dispersion relations for strongly coupled plasma fluids
Sergey Khrapak
Very simple explicit analytical expressions are discussed, which are able to describe the dispersion relations of longitudinal waves in strongly coupled plasma systems such as one-…
Nonlinear electrostatic oscillations in a cold magnetized electron-positron plasma
Prabal Singh Verma, Tapan Chandra Adhyapak
We study the spatio-temporal evolution of the nonlinear electrostatic oscillations in a cold magnetized electron-positron (e-p) plasma using both analytics and simulations. Using a…
Tractable flux-driven temperature, density, and rotation profile evolution with the quasilinear gyrokinetic transport model QuaLiKiz
J Citrin, C Bourdelle, F J Casson +14
Quasilinear turbulent transport models are a successful tool for prediction of core tokamak plasma profiles in many regimes. Their success hinges on the reproduction of local nonli…
Cross-code gyrokinetic verification and benchmark on the linear collisionless dynamics of the geodesic acoustic mode
A. Biancalani, A. Bottino, C. Ehrlacher +10
The linear properties of the geodesic acoustic modes (GAM) in tokamaks are investigated by means of the comparison of analytical theory and gyrokinetic numerical simulations. The d…
Experimental observations and modelling of intrinsic rotation reversals in tokamaks
Y. Camenen, C. Angioni, A. Bortolon +8
The progress made in understanding spontaneous toroidal rotation reversals in tokamaks is reviewed and current ideas to solve this ten-year-old puzzle are explored. The paper inclu…
