Parton Hadron Quantum Molecular Dynamics (PHQMD)  a Novel Microscopic NBody Transport Approach for HeavyIon Dynamics and Hypernuclei Production
[arXiv:1911.11892]
We present the novel microscopic nbody dynamical transport approach PHQMD(PartonHadronQuantumMolecularDynamics) for the description of particle production and cluster formation in heavyion reactions at relativistic energies. The PHQMD extends the established PHSD (PartonHadronStringDynamics) transport approach by replacing the mean field by density dependent two body interactions in a similar way as in the Quantum Molecular Dynamics (QMD) models. [...]

The PHQMD model for the formation of nuclear clusters and hypernuclei in heavyion collisions
[arXiv:1911.09496]
Modeling of the process of the formation of nuclear clusters in the hot nuclear matter is a challenging task. We present the novel nbody dynamical transport approach  PHQMD (PartonHadronQuantumMolecular Dynamics) [1] for the description of heavyion collisions as well as clusters and hpernuclei formation.

Transport coefficients for the hot quarkgluon plasma at finite chemical potential $\mu_B$
[arXiv:1911.08547]
We calculate transport coefficients of the quarkgluon plasma (QGP) within the dynamical quasiparticle model (DQPM) by explicitly computing the parton interaction rates as a function of temperature $T$ and baryon chemical potential $\mu_B$ on the basis of the DQPM couplings and partonic propagators. The latter are extracted from lattice QCD by matching the equation of state, entropy density and energy density at $\mu_B$= 0. [...]

Transport coefficients of hot and dense matter
[arXiv:1911.03131]
We present calculations for the shear viscosity of the hot and dense quarkgluon plasma (QGP) using the partonic scattering cross sections as a function of temperature $T$ and baryon chemical potential $\mu_B$ from the dynamical quasiparticle model (DQPM) that is matched to reproduce the equation of state of the partonic system above the deconfinement temperature $T_c$ from lattice QCD. To this aim we calculate the collisional widths for the partonic degrees of freedom at finite $T$ and $\mu_B$ in the timelike sector and conclude that the quasiparticle limit holds sufficiently well.

Exploring nonequilibrium quarkgluon plasma effects on charm transport coefficients
[arXiv:1910.09889]
In this article we investigate how the drag coefficient $A$ and $\hat{q}$, the transverse momentum transfer by unit length, of charm quarks are modified if the QGP is not in complete thermal equilibrium using the dynamical quasiparticle model (DQPM) which reproduces both, the equationofstate of the QGP and the spatial diffusion coefficient of heavy quarks as predicted by lattice QCD calculations. We study three cases: a) the QGP has an anisotropic momentum distribution of the partons which leads to an anisotropic pressure b) the QGP partons have higher or lower kinetic energies as compared to the thermal expectation value, and c) the QGP partons have larger or smaller pole masses of their spectral function as compared to the pole mass from the DQPM at the QGP temperature.

PHSD  a microscopic transport approach for strongly interacting systems
[arXiv:1908.00451]
We present the basic ideas of the PartonHadronString Dynamics (PHSD) transport approach which is a microscopic covariant dynamical model for strongly interacting systems formulated on the basis of KadanoffBaym equations for Green's functions in phasespace representation (in 1st order gradient expansion beyond the quasiparticle approximation). The approach consistently describes the full evolution of a relativistic heavyion collision from the initial hard scatterings and string formation through the dynamical deconfinement phase transition to the stronglyinteracting quarkgluon plasma (sQGP) as well as hadronization and the subsequent interactions in the expanding hadronic phase.

[arXiv:1907.03860]
Cluster and hypernuclei production in heavyion collisions is presently under active experimental and theoretical investigation. Since clusters are weekly bound objects, their production is very sensitive to the dynamical evolution of the system and its interactions. [...]
