Statistical Mechanics of Quarkyonic Matter
Marcus Bluhm, Yuki Fujimoto, Marlene Nahrgang
We extend the theoretical formulation of Quarkyonic Matter within the IdylliQ model framework proposed in [Y. Fujimoto et al., Phys. Rev. Lett. 132, 112701 (2024) [1]] for zero tem…
Quark saturation in the QCD phase diagram
Marcus Bluhm, Yuki Fujimoto, Larry McLerran +1
We determine the onset of Quarkyonic Matter corresponding to values of temperature and baryon chemical potential at which the quark phase space density becomes one. At zero tempera…
Renormalized critical dynamics and fluctuations in model A
Nadine Attieh, Nathan Touroux, Marcus Bluhm +3
In the context of relativistic heavy-ion collisions, we explore the stochastic and dissipative relaxational dynamics of a non-conserved order parameter in a interaction. The…

Jan Hammelmann, Marcus Bluhm, Marlene Nahrang +1
We study the evolution of critical fluctuations in an expanding system within a hadronic transport approach. The initialization of the system with critical fluctuations is achieved…

Grégoire Pihan, Marcus Bluhm, Masakiyo Kitazawa +2
In this work we study the consequences of a longitudinal Bjorken expansion and a Hubble-like temperature cooling scenario on a 1+1D non-linear model of the diffusive dynamics of fl…

The Beam Energy Scan Theory (BEST) Collaboration was formed with the goal of providing a theoretical framework for analyzing data from the Beam Energy Scan (BES) program at the rel…

The experimental search for the QCD critical point by means of relativistic heavy-ion collisions necessitates the development of dynamical models of fluctuations. In this work we s…

Marcus Bluhm, Marlene Nahrgang, Jan M. Pawlowski
Based on transport equations we argue that the chiral dynamics in heavy-ion collisions at high collision energies effectively decouples from the thermal physics of the fireball. Wi…

For the discovery of the QCD critical point it is crucial to develop dynamical models of the fluctuations of the net-baryon number that can be embedded in simulations of heavy-ion…
