Chaos in QCD? Gap equations and their fractal properties
T. Klaehn, L. C. Loveridge, M. Cierniak
We discuss how iterative solutions of QCD inspired gap-equations at finite chemical potential show domains of chaotic behavior as well as non-chaotic domains which represent one or…
Equation of state constraints from the threshold binary mass for prompt collapse of neutron star mergers
Andreas Bauswein, Sebastian Blacker, Vimal Vijayan +7
Using hydrodynamical simulations for a large set of high-density matter equations of state (EoSs) we systematically determine the threshold mass M_thres for prompt black-hole forma…
Impact of the Nuclear Equation of State on the Stability of Hybrid Neutron Stars
Mateusz Cierniak, Tobias Fischer, Niels-Uwe Bastian +2
We construct a set of equations of state (EoS) of dense and hot matter with a 1st order phase transition from a hadronic system to a deconfined quark matter state. In this two-phas…
Vector-Interaction-Enhanced Bag Model
Mateusz Cierniak, Thomas Klähn, Tobias Fischer +1
A commonly applied quark matter model in astrophysics is the thermodynamic bag model (tdBAG). The original MIT bag model approximates the effect of quark confinement, but does not…
Exploring the In-Medium Momentum Dependence of the Dynamical Quark Mass
Mateusz Cierniak, Thomas Klähn
We review the two standard equations of states based on the Nambu-Jona-Lasinio (NJL) model and the thermodynamic bag (tdBag) model for dense, cold quark matter from a perspective b…
