SUMMARY:From SOL turbulence to planetary magnetospheres: computational
  plasma physics at (almost) all scales using the Gkeyll code\, Plasma 
 Physics (Physics/ECE/NE 922) Seminar\, Dr. Ammar Hakim \, Princeton Pl
 asma Physics Laboratory
DESCRIPTION:Gkeyll is a computational plasma physics package that aims
  to simulate plasmas at (almost) all scales. At present\, the code con
 tains solvers for three major equation systems: Vlasov-Maxwell equatio
 ns\, electromagnetic gyrokinetic equations and multi-fluid moment equa
 tions. These span the complete range of plasma physics\; electromagnet
 ic shocks\, turbulence and first-principles sheath physics\, requiring
  full kinetic treatment\; turbulence in tokamak core and SOL\, requiri
 ng EM gyrokinetics\; and planetary magnetospheres\, requiring fluid tr
 eatment with proper accounting of kinetic effects to capture reconnect
 ion and current sheet dynamics. In this talk I will present an overvie
 w of our recent results in performing the first nonlinear full-f\, ele
 ctromagnetic gyrokinetic continuum simulations of scrape-off-layer tur
 bulence and the key algorithmic innovations made. I will also present 
 results from simulations of Mercury's magnetosphere using our advanced
  multi-moment multifluid solver. I will conclude with an overview of o
 ur program\, funded by ARAP-E\, to study (amongst other things) equili
 brium\, stability and transport of the University of Wisconsin WHAM mi
