论文摘要
在自洽的核能密度功能理论的框架内研究了热中子 - 普罗顿超流体混合物中的相互夹带效应。我们从有限温度下的时间依赖性的hartree-fock-bogoliubov方程中得出的均匀或不均匀核系统中的局部质量流，显示出与在零温度下没有配对的情况下发现的正式表达。获得夹带矩阵的分析表达式用于应用超流体中子星核。将结果与使用Landau理论先前获得的结果进行了比较。我们的公式适用于任意温度和电流，适用于已经计算出的统一状态方程的各种功能，包括统一的状态方程，从而为超级富集中子星的完全一致的显微镜描述奠定了基础。
Mutual entrainment effects in hot neutron-proton superfluid mixtures are studied in the framework of the self-consistent nuclear energy-density functional theory. The local mass currents in homogeneous or inhomogeneous nuclear systems, which we derive from the time-dependent Hartree-Fock-Bogoliubov equations at finite temperatures, are shown to have the same formal expression as the ones we found earlier in the absence of pairing at zero temperature. Analytical expressions for the entrainment matrix are obtained for application to superfluid neutron-star cores. Results are compared to those obtained earlier using Landau's theory. Our formulas, valid for arbitrary temperatures and currents, are applicable to various types of functionals including the Brussels-Montreal series for which unified equations of state have been already calculated, thus laying the ground for a fully consistent microscopic description of superfluid neutron stars.
