DESCRIPTION:Particle-in-cell methods solve the Maxwell equations for the e
 lectromagnetic&#12\;eld in combination with the equation of motion for the
  charged particles in aplasma. The motion of charegd particles is usually 
 computed using the Boris algorithm\,a variant of St&#127\;ormer{Verlet for
  Lorentz force omputations\, which has impressiveperformance and order two
  (like St&#127\;ormer{Verlet). Spectral deferred correction is aniterative
  time stepping method based on collocation\, which in each time step perfo
 rmsmultiple sweeps of a low-order method (here\, the Boris method) in orde
 r to obtain ahigh-order approximation. This talk describes the ongoing e&#
 11\;orts of Kristo&#11\;er Smedt\,Daniel Ruprecht\, Steve Tobias and the s
 peaker to embed a spectral deferred correctiontime stepper based on the Bo
 ris method in a particle-in-cell method.
