We study the spectral properties of an overoccupied gluonic system far from equilibrium. Using classical Yang–Mills simulations and linear response theory, we determine the statistical and spectral functions. We measure dispersion relations and damping rates of transversally and longitudinally polarized excitations in the gluonic plasma, and also study further structures in the spectral function.

Spectral function for overoccupied gluodynamics from real-time lattice simulations
Boguslavski, Kirill; Kurkela, A.; Lappi, Tuomas; Peuron, Jarkko (American Physical Society, 2018)We study the spectral properties of a highly occupied non-Abelian nonequilibrium plasma appearing ubiquitously in weak coupling descriptions of QCD matter. The spectral function of this far-fromequilibrium plasma is ... -
Quasiparticle properties of nonequilibrium gluon plasma
Peuron, Jarkko (University of Jyväskylä, 2018)We apply classical gluodynamics to early stages of ultrarelativistic heavy-ion collisions. We start by giving a brief overview of QCD. Then we proceed to the space-time evolution of ultrarelativistic heavy-ion collisions ... -
Spectral function of fermions in a highly occupied non-Abelian plasma
Boguslavski, K.; Lappi, T.; Mace, M.; Schlichting, S. (Elsevier BV, 2022)We develop a method to obtain fermion spectral functions non-perturbatively in a non-Abelian gauge theory with high occupation numbers of gauge fields. After recovering the free field case, we extract the spectral function ... -
Probing spectral properties of the QGP with real-time lattice simulations
Boguslavski, K.; Kurkela, A.; Lappi, T. Peuron, J. (Sissa Medialab srl, 2019)We present a new method to obtain spectral properties of a non-Abelian gauge theory in the region where occupation numbers are high. The method to measure the (single-particle) spectral function is based on linear response ... -
Effective Field Theory and Lattice QCD approaches for hard probes in QCD matter
Escobedo Espinosa, M.A. (Sissa Medialab srl, 2019)Hard Probes are an essential tool to discover the properties of the quark-gluon plasma created in heavy-ion collisions. The study of hard probes always involves taking into account very different energy scales, and this ...
