Two electrostatic gyrokinetic models derived by two different perturbative methods
Shuangxi Zhang
This paper presents two different electrostatic gyrokinetic models derived through two different perturbative methods. One of the two models is just the conventional electrostatic…
On the gyrocenter transform implemented on Lagrangian differential 1-form with the existence of magnetic perturbation
Shuangxi Zhang
This paper pointed out that the usual gyrocenter transform, which implements single-parameter Lie transform perturbation theory on Lagrangian differential 1-form of the orbit of ch…
Modelling the Lagrangian of magnetized plasmas with low-frequency magnetic perturbations by a gyrokinetic Ampere-Poisson model
Shuangxi Zhang
Following the method in Ref.(1), this paper introduces a fundamental Lagrangian 1-form on the particle's coordinates, which determines the dynamics of all ions and electrons of the…
Guiding-center kinetic model based on the assumption of homogeneous distribution over gyrophase
Shuangxi Zhang
The purpose of this paper is to develop a simplified model as the modeling of the magnetized plasmas. The starting point is an assumption that the distribution of the ensemble of c…
