White dwarf-neutron star matter transition and the effect of light elements
Yao Ma, Yong-Liang Ma, Ruo-Xi Wu +1
White dwarfs and neutron stars are unique laboratories for dense nuclear matter physics. We develop a single relativistic mean-field framework that treats both classes of compact s…
NNStar: An end-to-end AI agent for nuclear matter and neutron star physics
Yao Ma, Yong-Liang Ma, Jia-Ying Xiong
Constraining the equation of state of dense matter requires confronting effective models with massive data that spans many orders of magnitude in scale, from sub-saturation nuclear…
Nuclear matter properties and neutron star structures from an extended linear sigma model
Yao Ma
The properties of nuclear matter and the structures of neutron stars are analyzed with a baryonic extended linear sigma model in mean-field approximation, where the masses of baryo…
Neutron star structure and nuclear matter properties from a general Walecka-type model with Bayesian analysis
Yao Ma, Jia-Ying Xiong
We establish a Bayesian analysis framework with a general Walecka-type relativistic mean-field model to study dense nuclear matter under constraints from nuclear matter properties…
Hadronic description of nuclear matter and neutron star properties
Yao Ma, Yong-Liang Ma, Jia-Ying Xiong
The composition of the neutron star is one of the most fundamental and long-standing problems in nuclear- and astro-physics. The known properties of nuclear matter, together with t…
Compact star and compact star matter properties from a baryonic extended linear sigma model with explicit chiral symmetry breaking
Yao Ma, Yong-Liang Ma, Lu-Qi Zhang
Based on a baryonic extended linear sigma model including explicit chiral symmetry breaking effect, the structure of neutron stars with the emergence of hyperons is investigated us…
Composition of scalar mesons and their effects on nuclear matter properties in an extended linear sigma model
Yao Ma, Yong-Liang Ma
It has been argued that the iso-scalar and iso-vector mesons play significant roles in nuclear matter and neutron star structures. We improve the extended linear sigma model with b…
White Dwarf Structure and Binary Inspiral Gravitational Waves from Quantum Hadrodynamics
Ling-Jun Guo, Yao Ma, Yong-Liang Ma +2
White dwarfs, one of the compact objects in the universe, play a crucial role in astrophysical research and provide a platform for exploring nuclear physics. In this work, we exten…
Peak of sound velocity, scale symmetry, and nuclear force in baryonic matter
Lu-Qi Zhang, Yao Ma, Yong-Liang Ma
The sound velocity in homogeneous matter has fundamental significance as it relates to the stiffness of the equation of state of compact star matter. In this work, we investigate t…
Quark structure of isoscalar- and isovector-scalar mesons and nuclear matter property
Yao Ma, Yong-Liang Ma
It was found that the isoscalar-scalar and isovector-scalar mesons play significant roles in nuclear matter physics. However, the underlying structures of these resonances are not…
Insights into neutron star equation of state by machine learning
Ling-Jun Guo, Jia-Ying Xiong, Yao Ma +1
Due to its powerful capability and high efficiency in big data analysis, machine learning has been applied in various fields. We construct a neural network platform to constrain th…
Dispersive analysis of low energy process
Xiong-Hui Cao, Yao Ma, Han-Qing Zheng
We use a dispersion representation based on unitarity and analyticity to study the low energy process in the channel. Final state interactions among…
