Nonequilibrium dynamics and transport near the chiral phase transition of a quark-meson model
Alex Meistrenko, Christian Wesp, Hendrik van Hees +1
Based on the 2PI quantum effective action of the linear sigma model with constituent quarks, we develop a transport approach to study systems out of equilibrium. In particular, we…
RHIC and LHC phenomena with an unified parton transport
Ioannis Bouras, Andrej El, Oliver Fochler +6
We discuss recent applications of the partonic pQCD based cascade model BAMPS with focus on heavy-ion phenomeneology in hard and soft momentum range. The nuclear modification facto…
A Monte Carlo framework for noncontinuous interactions between particles and classical fields
Christian Wesp, Hendrik van Hees, Alex Meistrenko +1
Particles and fields are standard components in numerical simulations like transport simulations in nuclear physics and have very well understood dynamics. Still, a common problem…
Monte-Carlo approach to particle-field interactions and the kinetics of the chiral phase transition
Carsten Greiner, Christian Wesp, Hendrik van Hees +1
The kinetics of the chiral phase transition is studied within a linear quark-meson- model, using a Monte-Carlo approach to semiclassical particle-field dynamics. The meson fiel…
Shear viscosity of an ultrarelativistic Boltzmann gas with isotropic inelastic scattering processes
Andrej El, Francesco Lauciello, Christian Wesp +3
We derive an analytic expression for the shear viscosity of an ultra-relativistic gas in presence of both elastic and inelastic processes with isotrop…
Dissipative hydrodynamics for multi-component systems
Andrej El, Ioannis Bouras, Christian Wesp +2
Second-order dissipative hydrodynamic equations for each component of a multi-component system are derived using the entropy principle. Comparison of the solutions with kinetic tra…
Elliptic flow and nuclear modification factor in ultra-relativistic heavy-ion collisions within a partonic transport model
Jan Uphoff, Oliver Fochler, Florian Senzel +3
The quark gluon plasma produced in ultra-relativistic heavy-ion collisions exhibits remarkable features. It behaves like a nearly perfect liquid with a small shear viscosity to ent…
