From hadrons to quarks in neutron stars: a review

G Baym, T Hatsuda, T Kojo, PD Powell… - Reports on Progress …, 2018 - iopscience.iop.org
In recent years our understanding of neutron stars has advanced remarkably, thanks to
research converging from many directions. The importance of understanding neutron star …

Trace anomaly as signature of conformality in neutron stars

Y Fujimoto, K Fukushima, LD McLerran… - Physical Review Letters, 2022 - APS
We discuss an interpretation that a peak in the sound velocity in neutron star matter, as
suggested by the observational data, signifies strongly coupled conformal matter. The …

Chiral restoration of nucleons in neutron star matter: Studies based on a parity doublet model

T Minamikawa, B Gao, T Kojo, M Harada - Symmetry, 2023 - mdpi.com
We review the chiral variant and invariant components of nucleon masses and the
consequence of their existence on the chiral restoration in extreme conditions, particularly in …

Quarkyonic matter and neutron stars

L McLerran, S Reddy - Physical review letters, 2019 - APS
We consider quarkyonic matter to naturally explain the observed properties of neutron stars.
We argue that such matter might exist at densities close to that of nuclear matter, and at the …

Reaching percolation and conformal limits in neutron stars

M Marczenko, L McLerran, K Redlich, C Sasaki - Physical Review C, 2023 - APS
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 …

Phase transition phenomenology with nonparametric representations of the neutron star equation of state

R Essick, I Legred, K Chatziioannou, S Han, P Landry - Physical Review D, 2023 - APS
Astrophysical observations of neutron stars probe the structure of dense nuclear matter and
have the potential to reveal phase transitions at high densities. Most recent analyses are …

Map** neutron star data to the equation of state using the deep neural network

Y Fujimoto, K Fukushima, K Murase - Physical Review D, 2020 - APS
The densest state of matter in the Universe is uniquely realized inside the central cores of
the neutron star. While first-principles evaluation of the equation of state of such matter …

Momentum shell in quarkyonic matter from explicit duality: A dual model for cold, dense QCD

Y Fujimoto, T Kojo, LD McLerran - Physical Review Letters, 2024 - APS
We present a model of cold QCD matter that bridges nuclear and quark matter through the
duality relation between quarks and baryons. The baryon number and energy densities are …

Reconstructing the neutron star equation of state from observational data via automatic differentiation

S Soma, L Wang, S Shi, H Stöcker, K Zhou - Physical Review D, 2023 - APS
Neutron star observables like masses, radii, and tidal deformability are direct probes to the
dense matter equation of state (EoS). A novel deep learning method that optimizes an EoS …

Treating quarks within neutron stars

S Han, MAA Mamun, S Lalit, C Constantinou… - Physical Review D, 2019 - APS
Neutron star interiors provide the opportunity to probe properties of cold dense matter in the
QCD phase diagram. Utilizing models of dense matter in accord with nuclear systematics at …
