Hadronization of correlated gluon fields Open
Following an explicit example, we present the chain of steps required for an\nevent-by-event description of hadron production in high energy hadronic and\nnuclear collisions. We start from incoming nuclei, described in the Color Glass\nCon…
Cross-conductivity: Novel transport coefficients to constrain the hadronic degrees of freedom of nuclear matter Open
In general, the constituents of the bulk matter produced in heavy-ion\ncollisions carry, besides electric charge, multiple other conserved quantum\nnumbers like baryon number and strangeness. Therefore, an electric field will\nnot only gen…
Diffusion processes involving multiple conserved charges: A study from kinetic theory and implications to the fluid-dynamical modeling of heavy ion collisions Open
The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number, and strangeness. Therefore, the diffusion processes associated with these conserved charges cannot o…

Electrical conductivity and relaxation via colored noise in a hadronic gas Open
Motivated by the theory of relativistic hydrodynamic fluctuations we make use\nof the Green-Kubo formula to compute the electrical conductivity and the\n(second-order) relaxation time of the electric current of an interacting hadron\ngas. …
Diffusion of Conserved Charges in Relativistic Heavy Ion Collisions Open
We discuss the diffusion currents occurring in a dilute system and show that the charge currents do not only depend on gradients in the corresponding charge density, but also on the other conserved charges in the system—the diffusion…
Importance of initial and final state effects for azimuthal correlations in p+Pb collisions Open
We study the influence and interplay of initial state and final state effects in the dynamics of small systems, focusing on azimuthal correlations at different multiplicities. To this end we introduce a new model, matching the classical Ya…
Improving the LPM effect in BAMPS Open
Several analytic calculations of radiative jet energy loss demonstrated the importance of the non Abelian Landau-Pomeranchuk-Migdal (LPM) effect, a coherence effect resulting from the finite formation time of emitted gluons. While in these…
Diffusion of Conserved Charges in Relativistic Heavy Ion Collisions Open
We demonstrate that the diffusion currents do not depend only on gradients of their corresponding charge density, but that the different diffusion charge currents are coupled. This happens in such a way that it is possible for density grad…
Collectivity in small systems - Initial state vs. final state effects Open
Observations of long rang azimuthal correlations in small collision systems (p+p/A) have triggered an enormous excitement in the heavy-ion community. However, it is presently unclear to what extent the experimentally observed correlations …
Erratum: Electric conductivity of a hot hadron gas from a kinetic approach [Phys. Rev. D <b>93</b>, 096012 (2016)] Open
We calculate the electric conductivity of a gas of relativistic particles with isotropic cross sections using the Boltzmann equation as the starting point. Our analyses is restricted to elastic collisions. We show the perfect agreement wit…
Magnetic field influence on the early-time dynamics of heavy-ion collisions Open
In high energy heavy-ion collisions the magnetic field is very strong right\nafter the nuclei penetrate each other and a non-equilibrium system of quarks\nand gluons builds up. Even though quarks might not be very abundant initially,\nthei…
Nonequilibrium photon production in partonic transport simulations Open
We discuss the implementation of leading-order photon production in\nnonequilibrium partonic transport simulations. In this framework photons are\nproduced by microscopic scatterings, where we include the exact matrix elements\nof Compton …
