Rapidly Spinning Massive Pulsars as an Indicator of Quark Deconfinement
Christoph Gärtlein, Violetta Sagun, Oleksii Ivanytskyi +2
We study rotating hybrid stars, with particular emphasis on the effect of spin on the deconfinement phase transition and star properties. Our analysis is based on a hybrid equation…
Generalized Beth--Uhlenbeck entropy formula from the derivable approach
David Blaschke, Gerd Röpke, Gordon Baym
We derive a generalized Beth-Uhlenbeck formula for the entropy of a dense fermion system with strong two-particle correlations, including scattering states and bound states. We wor…
Bayesian inference favors quark matter in neutron star interiors
Alexander Ayriyan, Oleksii Ivanytskyi, David Blaschke
We perform a physics-informed Bayesian analyses of the equation of state of hybrid neutron stars that incorporates color-flavor-locked quark matter modeled by a three-flavor non-lo…
Generalized Beth-Uhlenbeck approach to the thermodynamics of quark-hadron matter
David Blaschke, Oleksii Ivanytskyi, Gerd Röpke
We present a unified approach to the transition from hadronic matter to quark matter where hadrons are treated as bound states of quarks which dissociate at high densities due to q…
Speed of sound of QCD matter at chiral crossover
Oleksii Ivanytskyi, David Blaschke, Gerd Röpke
Based on a generalized Beth-Uhlenbeck approach to thermodynamics of QCD motivated by cluster decomposition we present a unified equation of state of hot strongly interacting matter…
Primordial black-hole formation and heavy r-process element synthesis from the cosmological QCD transition. Two aspects of an inhomogeneous early Universe
M. Gonin, G. Hasinger, D. Blaschke +2
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter candidates. We elucidate the role of phase trans…
