非对称核物质状态方程(核态方程)对不同核系统的静态物理性质及其动力学演化性质起着决定性的作用。非对称核物质状态方程主要包括对称核物质状态方程和对称能的密度依赖关系。两者尤其是后者在高密物质中具有很大的不确定性，特别是当高密物质中出现非核子自由度时，情况更趋复杂。本项目将包含超子、反K介子、夸克以及非标准模型粒子等非核子自由度，主要研究下面三个问题。 第一、通过同位旋标量的Λ超子优选核模型的对称能密度依赖关系，即要验证合适的对称能密度相关性是否使多Λ超子系统能量极小。第二、发生夸克相变的核物质中，超子组份可能使化学平衡难能达到，即要发现超子与介子场作用的介质效应而守持化学平衡。第三、在中子星物质中研究轻的非标准模型粒子对中微子输运的影响,并寻找与非对称核态方程敏感的性质。

The nuclear equation of state (EOS) of asymmetric matter plays a determining role in the statistic and dynamically evolutional properties in various nuclear systems. The EOS of asymmetric matter includes mainly the EOS of symmetric matter and the density dependence of the symmetry energy， both of which, especially the latter, have large uncertainties in high density matter. In particular, the situation becomes more complicated with the appearance of non-nucleonic degrees of freedom. In this project, we include the non-nucleonic degrees of freedom such as hyperons, antikaon mesons, quarks and particles in the Non-Standard Model. The research will focus on the following three aspects. First, utilizing the isoscalar Λ hyperons we aim to optimize the density dependence of the symmetry energy by examining whether it can minimize the energy of multi-Λ system. Second, In matter with hadron-quark phase transition, the chemical equilibrium can usually be disabled by the hyperon constituents. To rebuild the chemical equilibrium, we thus aim to seek for the appropriate in-medium effect for the interaction between the hyperon and mesons. Third, the effect of the light non-Standard Model particles on the neutrino transport in neutron star matter is going to be studied to find the signals sensitive to the EOS of asymmetric matter.
