Clebsch representation of relativistic plasma and generalized enstrophy
Keiichiro Nunotani, Zensho Yoshida
The dynamics of plasma can be formulated as a subalgebra of the Poisson manifold of the Clebsch fields. In this work, we extend this formulation to a Lorentz covariant form. We sho…

Kinetic construction of the high-beta anisotropic-pressure equilibrium in the magnetosphere
H. Aibara, Z. Yoshida, K. Shirahata
A theoretical model of the high-beta equilibrium of magnetospheric plasma was constructed by consistently connecting the (anisotropic pressure) Grad-Shafranov equation and the Vlas…

The kinetic origin of the fluid helicity -- a symmetry in the kinetic phase space
Zensho Yoshida, Philip J. Morrison
Helicity, a topological degree that measures the winding and linking of vortex lines, is preserved by ideal (barotropic) fluid dynamics. In the context of the Hamiltonian descripti…
