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…

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…
