UPIC-Emma [1] is a new fully relativistic, fully parallelized, multidimensional electromagnetic spectral PIC code  built from components from the UPIC Framework. It uses a fully spectral (FFT) based field solver as described in  [2]. It includes the ability to launch laser pulses in both the lab and Lorentz boosted frame. It includes options for eliminating the robust numerical instability (Numerical Cherenkov Instability-NCI) that arises when the plasma drifts across the grid relativistically. This is accomplished by modifying the field solver near NCI unstable modes in  k-space which can be pinpointed based on recent theoretical work in [3-4]. It is currently being developed to study laser wakefield acceleration and relativistic shocks.
