Overview

Randomized trial demonstrates stability in quasineutral plasmas with thermalized electrons, indicating robust convergence under perturbations.

Key Points

  • This research investigates the stability of the quasineutral limit for an ionic Vlasov-Poisson system with thermalized electrons.
  • Utilized a kinetic-Wasserstein stability framework for analysis of VPME on the torus.
  • Focused on improving characteristic flow control to achieve quantitative bounds.
  • Established stability estimates for perturbed solutions based on reference solutions.
  • Proved that quasineutral convergence remains robust under exponentially small perturbations in Wasserstein distance.
  • Achieved new bounds on spatial density with only polynomial deterioration in the Debye length.
  • Relaxed smallness conditions from previous studies, enhancing the moment assumptions in global well-posedness theory.
