In recent years, there have been important advances in understanding the far-from-equilibrium dynamics in different physical systems. In ultra-relativistic heavy-ion collisions, the combination of different methods led to the development of a weak-coupling description of the early-time dynamics. The numerical observation of a classical universal attractor played a crucial role for this. Such attractors, also known as non-thermal fixed points (NTFPs), have been now predicted for different scalar and gauge theories. An important universal NTFP emerges in scalar theories modeling ultra-cold atoms, inflation or dark matter, and its scaling properties have been recently observed in an ultra-cold atom experiment. In this proceeding, recent progress in selected topics of the far-from-equilibrium evolution in these systems will be discussed. A new method to extract the spectral function numerically is a particularly promising tool to better understand their microscopic properties.

Non-equilibrium dynamics of a scalar field with quantum backreaction
Kainulainen, Kimmo; Koskivaara, Olli (Springer, 2021)We study the dynamical evolution of coupled one- and two-point functions of a scalar field in the 2PI framework at the Hartree approximation, including backreaction from out-of-equilibrium modes. We renormalize the 2PI ... -
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 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 ... -
Neutrino density matrix formalism derived from Kadanoff-Baym equations
Parkkinen, Harri (2020)Edetessään väliaineessa neutriinojen ja materian välillä tapahtuu kahdenlaisia törmäyksiä: koherentteja ja epäkoherentteja törmäyksiä. Koherentit törmäykset aiheuttavat taustapotentiaalin, joka muuttaa neutriinojen ... -
Spectral function for overoccupied gluodynamics from classical lattice simulations
Boguslavski, Kirill; Kurkela, Aleksi; Lappi, Tuomas; Peuron, Jarkko (Jagellonian University, 2019)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 ...
