The colored particle-in-cell simulations can simulate the production and evolution of the Glasma.
Previous particle-in-cell codes for electromagnetic plasmas are currently not maintained.

About Glasma simulations

The Glasma is a precursor state to the quark-gluon plasma. It is created when two highly Lorentz-contracted nuclei collide at ultra-relativistic energies. We have created an open-source framework for the simulation of the initial stages of heavy ion collisions. This framework is inspired by the particle-in-cell method which is used for simulating electromagnetic plasmas. In our case, we apply this method to the strong nuclear force, also called color force, with concepts borrowed from lattice gauge theory.
