SUMMARY:Eulerian Energization in Reconnection and Turbulence\, Plasma 
 Physics (Physics/ECE/NE 922) Seminar\, Jason Tenbarge\, Princeton Plas
 ma Physics Laboratory
DESCRIPTION:Turbulence and magnetic reconnection are ubiquitous proces
 ses in space and astrophysical plasmas\, and they play fundamental rol
 es in transforming magnetic energy into kinetic and internal energies.
  Particle energization\, especially in the context of reconnection\, h
 as frequently been examined from a particle\, or Lagrangian\, perspect
 ive employing guiding-center analyses to particle-in-cell (PIC) simula
 tions. These analyses of PIC particles have suggested that Fermi (curv
 ature drift) acceleration and direct acceleration via the reconnection
  electric field are the primary electron energization mechanisms. Howe
 ver\, both PIC guiding-center analyses and spacecraft observations are
  performed in an Eulerian frame. We employ continuum kinetic simulatio
 ns using the Gkeyll simulation framework and the Hybrid-Vlasov–Maxwe
 ll (HVM) code to re-examine energization from a continuum\, Eulerian p
 erspective. We separately examine the contribution of each drift energ
 ization component to determine the dominant energization mechanisms in
  a moderate guide-field Gkeyll reconnection simulation as well as in H
 VM turbulence simulations. We compare the Eulerian results with the wi
 sdom gained from Lagrangian (PIC) analyses.
