Proton-neutron correlations in baryon-number fluctuations near the liquid-gas transition
Michał Marczenko
We study net-baryon number density fluctuations in isospin-symmetric matter near the nuclear liquid-gas phase transition using the parity doublet model. We analyze second-order sus…
Suppression of dynamical momentum-space shell by chiral symmetry
Bikai Gao, Michał Marczenko
We investigate the appearance of quark degrees of freedom in dense isospin-symmetric nuclear matter. We employ the parity doublet model to incorporate chiral dynamics. Specifically…
Probing nuclear liquid-gas phase transition with isospin correlations
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
We investigate the fluctuations of the net-baryon number near the critical point of the liquid-gas phase transition. We use the parity doublet model in the mean-field approximation…
Average speed of sound in neutron stars
Michał Marczenko
The structure of the dense-matter equation of state is essential for the phenomenology of neutron stars. In this work, I relate the thermodynamic properties to the average speed of…
Interplay of baryonic chiral partners in fluctuations of net-baryon number density
Michał Marczenko, Volker Koch, Krzysztof Redlich +1
In this contribution, we use the parity doublet model to investigate the fluctuations of the net-baryon number density. We discuss the systematics of the susceptibilities and their…
Curvature of the energy per particle in neutron stars
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
Neutron stars (NSs) serve as laboratories for probing strongly interacting matter at the most extreme densities. Their inner cores are expected to be dense enough to host deconfine…
Fluctuations near the liquid-gas and chiral phase transitions in hadronic matter
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
We investigate the fluctuations of the net-baryon number density in dense hadronic matter. Chiral dynamics is modeled via the parity doublet Lagrangian, and the mean-field approxim…
Conformality and percolation threshold in neutron stars
Michał Marczenko, Larry McLerran, Krzysztof Redlich +1
Speed of sound is given attention in multi-messenger astronomy as it encodes information of the dense matter equation of state. Recently the trace anomaly was proposed as a more in…
Reconciling Multi-messenger Constraints with Chiral Symmetry Restoration
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
We consider the parity doublet model for nucleonic and delta matter to investigate the structure of neutron stars. We show that it is possible to reconcile the multi-messenger astr…
Reaching percolation and conformal limits in neutron stars
Michał Marczenko, Larry McLerran, Krzysztof Redlich +1
Generating an ensemble of equations of state that fulfill multimessenger constraints, we statistically determine the properties of dense matter found inside neutron stars (NSs). We…
Chiral symmetry restoration and the matter formation in neutron stars
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
We analyze the effects of chiral symmetry restoration in hadronic matter, including the lowest-lying baryonic resonance based on the parity doublet model. We study the role of…
Reconciling multi-messenger constraints with chiral symmetry restoration
Michał Marczenko, Krzysztof Redlich, Chihiro Sasaki
We analyze the recent astrophysical constraints in the context of a hadronic equation of state (EoS), in which the baryonic matter is subject to chiral symmetry restoration. We sho…
Hybrid quark-hadron equation of state for multi-messenger astronomy
Michał Marczenko
We present the recent progress of the hybrid quark-meson-nucleon model for multi-messenger astronomy that unifies the thermodynamics of quark and hadronic degrees of freedom. The o…
Speed of sound and quark confinement inside neutron stars
Michał Marczenko
Several observations of high-mass neutron stars (NSs), as well as the first historic detection of the binary neutron star merger GW170817, have delivered stringent constraints on t…
Parity Doubling and the Dense Matter Phase Diagram under Constraints from Multi-Messenger Astronomy
Michał Marczenko, David Blaschke, Krzysztof Redlich +1
We extend the recently developed hybrid quark-meson-nucleon model by augmenting a six-point scalar interaction and investigate the consequences for neutron-star sequences in the ma…
Chiral symmetry restoration by parity doubling and the structure of neutron stars
Michał Marczenko, David Blaschke, Krzysztof Redlich +1
Recent lattice QCD studies at vanishing density exhibit the parity-doubling structure for the low-lying baryons around the chiral crossover temperature. This finding is likely an i…

Michał Marczenko, David Blaschke, Krzysztof Redlich +1
We investigate the equation of state for a recently developed hybrid quark-meson-nucleon model under neutron star conditions of equilibrium and charge neutrality. The model has…
Repulsive interactions and their effects on the thermodynamics of hadron gas
Pok Man Lo, Bengt Friman, Michal Marczenko +2
We compare two approaches in modeling repulsive interactions among hadrons: the excluded volume approximation and the S-matrix formalism. These are applied to study the thermodynam…
Additional strange resonances from Lattice QCD
Michał Marczenko
Recent Lattice QCD (LQCD) studies suggest that there are missing resonances in the strange sector of the Hadron Resonance Gas (HRG) model. By adopting the continuous Hagedorn mass…

Pok Man Lo, Michał Marczenko, Krzysztof Redlich +1
Based on recent Lattice QCD (LQCD) results obtained at finite temperature, we discuss modeling of the hadronic phase of QCD in the framework of Hadron Resonance Gas (HRG) with disc…
