    • Broad excitations in a 2+1D overoccupied gluon plasma 

      Boguslavski, Kirill; Kurkela, Eero Aleksi; Lappi, Tuomas; Peuron, Jarkko (Peer reviewed; Journal article, 2021-05)
      Motivated by the initial stages of high-energy heavy-ion collisions, we study excitations of far-from-equilibrium 2+1 dimensional gauge theories using classical-statistical lattice simulations. We evolve field perturbations ...

    • Heavy quark diffusion in an overoccupied gluon plasma 

      Boguslavski, Kirill; Kurkela, Aleksi; Lappi, Tuomas; Peuron, Jarkko (Peer reviewed; Journal article, 2020-09)
      We extract the heavy-quark diffusion coefficient κ and the resulting momentum broadening 〈p2〉 in a far-from-equilibrium non-Abelian plasma. We find several features in the time dependence of the momentum broadening: a short ...

    • Spectral function for overoccupied gluodynamics from classical lattice simulations 

      Boguslavski, Kirill; Kurkela, Aleksi; Lappi, Tuomas; Peuron, Jarkko (Peer reviewed; Journal article, 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 ...
