• Analytic structure of nonhydrodynamic modes in kinetic theory 

      Kurkela, Aleksi; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2019-09)
      How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ...
    • Opacity dependence of elliptic flow in kinetic theory 

      Kurkela, Aleksi; Wiedemann, Urs Achim; Wu, Bin (Peer reviewed; Journal article, 2019-09)
      The observation of large azimuthal anisotropies vn in the particle spectra of proton–proton (pp) and proton–nucleus (pA) collisions challenges fluid dynamic interpretations of vn, as it remains unclear how small collision ...
