# Gauge-invariant condensation in the nonequilibrium quark-gluon plasma

@article{Berges2020GaugeinvariantCI, title={Gauge-invariant condensation in the nonequilibrium quark-gluon plasma}, author={J urgen Berges and Kirill Boguslavski and Mark Mace and Jan M. Pawlowski}, journal={Physical Review D}, year={2020}, volume={102}, pages={034014} }

The large density of gluons, which is present shortly after a nuclear collision at very high energies, can lead to the formation of a condensate. We identify a gauge-invariant order parameter for condensation based on elementary nonperturbative excitations of the plasma, which are described by spatial Wilson loops. Using real-time lattice simulations, we demonstrate that a self-similar transport process towards low momenta builds up a macroscopic zero mode. Our findings reveal intriguing… Expand
