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 s…
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…
Fastest spinning millisecond pulsars: indicators for quark matter in neutron stars?
Christoph Gärtlein, Violetta Sagun, Oleksii Ivanytskyi +2
We study rotating hybrid stars, with a particular emphasis on the effect of a deconfinement phase transition on their properties at high spin. Our analysis is based on a hybrid equ…
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…
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…
