Dense and hot QCD at strong coupling

T Demircik, C Ecker, M Järvinen - Physical review X, 2022 - APS
We present a novel framework for the equation of state of dense and hot quantum
chromodynamics (QCD), which focuses on the region of the phase diagram relevant for …

Far-from-equilibrium bulk-viscous transport coefficients in neutron star mergers

Y Yang, M Hippert, E Speranza, J Noronha - Physical Review C, 2024 - APS
We investigate the weak-interaction-driven bulk-viscous transport properties of npe matter in
the neutrino transparent regime. Previous works assumed that the induced bulk viscosity …

Emergence of microphysical bulk viscosity in binary neutron star postmerger dynamics

ER Most, A Haber, SP Harris, Z Zhang… - The Astrophysical …, 2024 - iopscience.iop.org
In nuclear matter in isolated neutron stars, the flavor content (eg, proton fraction) is subject to
weak interactions, establishing flavor (β-) equilibrium. However, there can be deviations …

Equation of state at neutron-star densities and beyond from perturbative QCD

O Komoltsev, R Somasundaram, T Gorda, A Kurkela… - Physical Review D, 2024 - APS
We explore the consequences of imposing robust thermodynamic constraints arising from
perturbative quantum chromodynamics (QCD) when inferring the dense-matter equation-of …

Post-merger gravitational-wave signal from neutron-star binaries: a new look at an old problem

K Topolski, SD Tootle, L Rezzolla - The astrophysical journal, 2023 - iopscience.iop.org
The spectral properties of the post-merger gravitational-wave signal from a binary of neutron
stars encodes a variety of information about the features of the system and of the equation of …

Estimate for the bulk viscosity of strongly coupled quark matter using perturbative QCD and holography

J Cruz Rojas, T Gorda, C Hoyos, N Jokela… - Physical Review Letters, 2024 - APS
Modern hydrodynamic simulations of core-collapse supernovae and neutron-star mergers
require knowledge not only of the equilibrium properties of strongly interacting matter, but …

Exploring thermal effects of the hadron-quark matter transition in neutron star mergers

S Blacker, A Bauswein, S Typel - Physical Review D, 2023 - APS
We study the importance of the thermal behavior of the hadron-quark phase transition in
neutron star (NS) mergers. To this end, we devise a new scheme approximating thermal …

Hybrid approach to long-term binary neutron-star simulations

HHY Ng, JL Jiang, C Musolino, C Ecker, SD Tootle… - Physical Review D, 2024 - APS
One of the main challenges in the numerical modeling of binary neutron-star mergers are
long-term simulations of the postmerger remnant over timescales of the order of seconds …

Probing neutron-star matter in the lab: Similarities and differences between binary mergers and heavy-ion collisions

ER Most, A Motornenko, J Steinheimer, V Dexheimer… - Physical Review D, 2023 - APS
Binary neutron-star mergers and heavy-ion collisions are related through the properties of
the hot and dense nuclear matter formed during these extreme events. In particular, low …
