同位旋非对称核物质中核对称能与单核子势的解析关系

Analytical relations between nuclear symmetry energy and single-nucleon potentials in isospin asymmetric nuclear matter

Chang Xu, Bao-An Li, Lie-Wen Chen, Che Ming Ko

摘要:

利用Hugenholtz-Van Hove定理,我们导出了同位旋非对称核物质中用单核子势表示的二次和四次对称能量的一般表达式。这些分析关系是有用的,以获得更深入的了解,在我们的核对称性能量的知识,特别是在超饱和密度的不确定性的微观起源。作为例子,形式主义被应用到两个模型单核子势,广泛用于重离子反应的输运模型模拟。

英文摘要:

Using the Hugenholtz-Van Hove theorem, we derive general expressions for the quadratic and quartic symmetry energies in terms of single-nucleon potentials in isospin asymmetric nuclear matter. These analytical relations are useful for gaining deeper insights into the microscopic origins of the uncertainties in our knowledge on nuclear symmetry energies especially at supra-saturation densities. As examples, the formalism is applied to two model single-nucleon potentials that are widely used in transport model simulations of heavy-ion reactions.
