A dual grid geometric electromagnetic particle in cell method
Katharina Kormann, Eric Sonnendrücker
Geometric particle-in-cell discretizations have been derived based on a discretization of the fields that is conforming with the de Rham structure of the Maxwell's equation and a s…

Semi-Lagrangian methods for a plasma hybrid model with multi-species kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Eric Sonnendrücker
The semi-Lagrangian methods with the improved number of one-dimensional advections are proposed for a plasma hybrid model with kinetic ions and mass-less electrons. Two subsystems…
