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 ... -
Thouless-Valatin moment of inertia and removal of the spurious mode in the linear response theory
Kortelainen, Markus (IOP Publishing Ltd, 2020)Symmetry breaking at the mean-field level leads to an appearance of a symmetry restoring Nambu-Goldstone (NG) mode in the linear response theory. These modes represent a special kind of collective motion of the system. ... -
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 ... -
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 ... -
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 ...
