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…
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…
Color-superconducting quarkyonic matter
Christoph Gärtlein, Oleksii Ivanytskyi, Violetta Sagun +1
We explore the role of color superconductivity in quarkyonic matter under the conditions of color and electric neutrality at - and strong equilibrium, as relevant for neutron st…
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…
Quarkyonic picture of isospin QCD
Oleksii Ivanytskyi
We suggest a new look onto the thermodynamics of cold isospin QCD matter described within the quarkyonic framework, when confining forces are essential only for the momentum states…
