Structural Requirements for Ion-Acoustic Double Layers: A Parametric Perturbation Analysis of the Maxwellian Limit
Hamdi M. Abdelhamid, Abeer A. Mahmoud, Naoki Sato
The paper shows that ion‑acoustic double layers can form in plasmas when the electron distribution deviates from a strict Maxwellian, using two perturbation parameters to derive an…
A Collision Operator for Field-Mediated Interactions in General Relativistic Kinetic Theory
Naoki Sato
We develop a Hamiltonian framework for general relativistic kinetic theory on the cotangent bundle of a Lorentzian (pseudo-Riemannian) manifold. Starting from the geode…
Scattering Theory in Noncanonical Phase Space: A Drift-Kinetic Collision Operator for Weakly Collisional Plasmas
Naoki Sato, Philip J. Morrison
After developing a scattering theory for grazing collisions in general noncanonical phase spaces, we introduce a guiding center collision operator in five-dimensional phase space d…
Axisymmetric Dynamos Sustained by a Modified Ohm's Law in a Toroidal Volume
Naoki Sato, Kumiko Hori
This work tackles a significant challenge in dynamo theory: the possibility of long-term amplification and maintenance of an axisymmetric magnetic field. We introduce a novel model…
