Extended applicability domain of viscous anisotropic hydrodynamics in (2+1)-D Bjorken flow with transverse expansion
Yiyang Peng, Victor E. Ambrus, Clemens Werthmann +3
We perform (2+1)-D simulations of viscous anisotropic hydrodynamics (VAH) under boost-invariant and conformal conditions. Comparing both VAH and traditional viscous hydrodynamics w…
Friction terms in multi-fluid description of heavy-ion collisions
Clemens Werthmann, Iurii Karpenko, Pasi Huovinen
In multi-fluid description of heavy-ion collisions, the primary scatterings and particle production are described in terms of interaction between fluids, so called friction. These…
Adiabatic hydrodynamization and quasinormal modes of nonthermal attractors
Matisse De Lescluze, Michal P. Heller, Aleksas Mazeliauskas +2
Nonthermal attractors govern the emergent self-similar dynamics of far-from-equilibrium quantum systems, from ultrarelativistic nuclear collisions to cold-atom experiments. Within…
Experimentally accessible drive-induced attractor in a Fermi gas near unitarity
Michal P. Heller, Clemens Werthmann
Hydrodynamic attractors describe loss of sensitivity to initial conditions. Their earliest, expansion-driven stage is distinct from the later relaxation-driven mechanism and centra…
Collective dynamics in heavy and light-ion collisions -- II) Determining the origin of collective behavior in high-energy collisions
Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
Exploiting the first measurements of the same ion species in OO collisons at RHIC and LHC, we propose an observable to distinguish whether collective behavior builds up through a h…
Collective dynamics in heavy and light-ion collisions -- I) Kinetic Theory vs. Hydrodynamics
Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
High-energy nuclear collisions exhibit collective flow, which emerges as a dynamical response of the Quark-Gluon Plasma (QGP) to the initial state geometry of the collision. Collec…
