Quark-gluon plasma produced at the early stage of ultrarelativistic heavy ion collisions is unstable, if weakly coupled, due to the anisotropy of its momentum distribution. Chromomagnetic fields are spontaneously generated and can reach…
In the early stages of relativistic heavy-ion collisions, the momentum distribution of the quark-gluon plasma is anisotropic, leading to instabilities in the system due to chromomagnetic plasma modes. In this work, we consider the…

The quark-gluon plasma created in heavy-ion collisions is not in local thermal equilibrium at early times. Despite this, dissipative hydrodynamics describes the evolution of the energy-momentum tensor quite well after only roughly 0.5 - 1…
