Clustered Nature of Hot and Dense Nuclear Matter: A quantum statistical approach
G. Röpke, H. Pais, J. B. Natowitz +1
The equilibrium abundances of the light clusters H, H, He, He in hot nuclear matter at densities near the saturation density are of essential interest for nuclear p…
Confining density functional approach to the QCD phase diagram at low temperatures and thermal twin stars
David Blaschke, Oleksii Ivanytskyi
We present a density functional-based equation of state for warm, dense nuclear matter with a transition to deconfined quark matter for applications to simulations of supernova exp…
Universality and variability of the heavy r-process element abundance pattern from a nonequilibrium approach
David Blaschke, Friedrich K. Röpke, Gerd Röpke
A striking feature in the observed chemical composition of the majority of stars is the universality of the relative abundances of the heavy elements, although some outliers exist.…
Generalized Beth-Uhlenbeck Approach to the 2+1D Gross-Neveu Model
Biplab Mahato, David Blaschke
We study the thermodynamics of the (2+1) dimensional Gross-Neveu model inspired from graphene. We focus on the entropy density of the Gaussian fluctuation beyond the mean field. Th…
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…
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…
Primordial black-hole formation and heavy r-process element synthesis from the cosmological QCD transition. Two aspects of an inhomogeneous early Universe
M. Gonin, G. Hasinger, D. Blaschke +2
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter candidates. We elucidate the role of phase trans…
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…
Heavy element abundances from a universal primordial distribution
G. Roepke, D. Blaschke, F. K. Roepke
We present a freeze-out approach to the formation of heavy elements in expanding nuclear matter. Applying concepts used in the description of heavy-ion collisions or ternary fissio…
Beth-Uhlenbeck equation for the thermodynamics of fluctuations in a generalised 2+1D Gross-Neveu model
Biplab Mahato, David Blaschke, Dietmar Ebert
We study a generalized version of the Gross-Neveu model in 2+1 dimensions. The model is inspired from Graphene, which shows a linear dispersion relation near the Dirac points. The…
Formation of twin compact stars in low-mass X-ray binaries: Implications on eccentric and isolated millisecond pulsar populations
S. Chanlaridis, D. Ohse, D. E. Alvarez-Castillo +5
Millisecond pulsars (MSPs) are laboratories for stellar evolution, strong gravity, and ultra-dense matter. Although MSPs are thought to originate in low-mass X-ray binaries (LMXBs)…
