Particle-in-cell (PIC) simulations have been used since the 1950s to simulate electromagnetic plasmas. In a PIC simulation, charged particles are tracked on a fixed background grid on which Maxwell's equations are solved. We want to re-examine PIC simulations in order to better understand systematic errors involed. We recover and analyze known plasma instabilities like two-stream instability or Weibel instability. A reference simulation is implemented as an open source framework, and we invite other research groups to participate and collaborate. Eventually we want to apply PIC simulations to non-abelian gauge theories for so-called colored PIC (CPIC) simulations. This will enable us to simulate early dynamics of the quark-gluon-plasma, including the emergence and evolution of plasma instabilities.
