有限核和中子星的相对论性密度泛函理论

Relativistic density functional theory for finite nuclei and neutron stars

J. Piekarewicz

摘要:

目前的贡献的主要目标是一个教学介绍的中子星的迷人的世界,依靠相对论密度泛函理论。密度泛函理论为计算有限核和中子星的性质提供了一个强大的--也许是独特的--框架。考虑到中子星核心可能达到的巨大密度,这种理论框架从一开始就必须包含洛伦兹协变性和狭义相对论的基本原理。经过简短的历史的角度来看,我们提出了必要的细节,计算状态方程的致密,中子丰富的物质。由于状态方程是计算中子星结构所需的全部,我们讨论了核物理--特别是某些实验室实验--如何对富中子物质的行为提供重要的约束。

英文摘要:

The main goal of the present contribution is a pedagogical introduction to the fascinating world of neutron stars by relying on relativistic density functional theory. Density functional theory provides a powerful--and perhaps unique--framework for the calculation of both the properties of finite nuclei and neutron stars. Given the enormous densities that may be reached in the core of neutron stars, it is essential that such theoretical framework incorporates from the outset the basic principles of Lorentz covariance and special relativity. After a brief historical perspective, we present the necessary details required to compute the equation of state of dense, neutron-rich matter. As the equation of state is all that is needed to compute the structure of neutron stars, we discuss how nuclear physics--particularly certain kind of laboratory experiments--can provide significant constrains on the behavior of neutron-rich matter.
