Hydrodynamic attractors
Tilman Enss, Michal P. Heller, Alexandre Serantes +1
Attractors are effective low-dimensional structures, defined in a chosen set of observables, that trajectories from different initial states approach; hydrodynamic attractors are t…
Expansion attractor in classical Yang-Mills theory
Clemens Werthmann
Applications of the concept of a hydrodynamic attractor have been mostly constrained to the context of hydrodynamization in heavy ion collisions. Deepening the understanding of the…
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…
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…
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…
Quantifying the degree of hydrodynamic behaviour in heavy-ion collisions
Sören Schlichting, Clemens Werthmann
Exploiting the first measurements of the same ion species in O+O collisons at RHIC and LHC, we propose an experimentally accessible observable to distinguish whether collective beh…
Simulating collectivity in dense baryon matter with multiple fluids
Iurii Karpenko, Jakub Cimerman, Pasi Huovinen +1
We report on construction of a modern multi-fluid approach to heavy-ion collisions at FAIR/BES energies (MUFFIN) and show the reproduction of basic experimental observables in Au-A…
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…
Establishing the Range of Applicability of Hydrodynamics in High-Energy Collisions
Clemens Werthmann, Victor E. Ambruş, Sören Schlichting
We simulate the space-time dynamics of high-energy collisions based on a microscopic kinetic description, in order to determine the range of applicability of an effective descripti…
System size dependence of pre-equilibrium and applicability of hydrodynamics in heavy-ion collisions
Victor E. Ambruş, Sören Schlichting, Clemens Werthmann
We simulate the space-time dynamics of high-energy collisions based on a microscopic kinetic description, in order to determine the range of applicability of an effective descripti…
Attractors for Flow Observables in 2+1D Bjorken Flow
Victor E. Ambruş, Sören Schlichting, Clemens Werthmann
We examine the capabilities of second-order Israel-Stewart-type hydrodynamics to capture the early-time behaviour of the quark-gluon plasma created in heavy-ion collisions. We poin…
Establishing the Range of Applicability of Hydrodynamics in High-Energy Collisions
Victor E. Ambrus, S. Schlichting, C. Werthmann
We simulate the space-time dynamics of high-energy collisions based on a microscopic kinetic description in the conformal relaxation time approximation, in order to determine the r…
Statistical analysis of initial state and final state response in heavy-ion collisions
Nicolas Borghini, Marc Borrell, Nina Feld +3
We develop a general decomposition of an ensemble of initial density profiles in terms of an average state and a basis of modes that represent the event-by-event fluctuations of th…
