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…

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…

Bayesian analysis of hybrid neutron star EOS constraints within an instantaneous nonlocal chiral quark matter model

Alexander Ayriyan, David Blaschke, Juan Pablo Carlomagno +2

We present a physics-informed Bayesian analysis of equation of state constraints using observational data for masses, radii and tidal deformability of pulsars and a generic class o…
