非对称核物质中包含自旋轨道和张量项的Skyrme泛函线性响应理论

Linear response theory in asymmetric nuclear matter for Skyrme functionals including spin-orbit and tensor terms

D. Davesne, A. Pastore, J. Navarro

摘要:

本文将包含自旋轨道和张量项的Skyrme泛函的线性响应理论推广到无限大核物质的情形,得到了任意同位旋不对称的Skyrme泛函的线性响应理论.响应函数是通过求解代数方程组得到的,该方程组是明确给出的。自旋-同位旋强度函数分析了不同的密度,动量转移,不对称性和温度的条件。通过静态磁化率研究了不稳定性的存在,包括旋节线不稳定性。

英文摘要:

The formalism of linear response theory for a Skyrme functional including spin-orbit and tensor terms is generalized to the case of infinite nuclear matter with arbitrary isospin asymmetry. Response functions are obtained by solving an algebraic system of equations, which is explicitly given. Spin-isospin strength functions are analyzed varying the conditions of density, momentum transfer, asymmetry and temperature. The presence of instabilities, including the spinodal one, is studied by means of the static susceptibility.
