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…
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…
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…
Connecting dilaton thermal fluctuation with the Polyakov loop at finite temperature
Bing-Kai Sheng, Yong-Liang Ma
Understanding the character of the deconfinement phase transition is one of the fundamental challenges in particle physics. In this work, we derive a formula for the expectation va…
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…
