The first publication based on the skeleton codes recently appeared in Physics of Plasmas:
R. Scott Hughes, Joseph Wang, Viktor K. Decyk, and S. Peter Gary, “Effects of
variations in electron thermal velocity on the whistler anisotropy instability: Particle-in-
cell simulations,” Physics of Plasmas 23, 042106 (2016). DOI: 10.1063/1.4945748
This work made used of the 2D darwin code mdpic2 and studied whistler wave instabilities for solar wind parameters.
