AI 中文摘要
我们研究了由中子、质子和电子组成的超导中子星物质中作用在质子涡旋上的力，考虑了中子 - 质子子系统中的费米液体相互作用。虽然由涡旋磁场引起的电子散射力是已知的，但我们证明正常中子由于与超导质子的费米液体耦合也会对质子涡旋施加力。使用基于朗道费米液体理论的动力学方法，表明中子准粒子通过空间变化的凝聚动量从质子涡旋散射，产生与相对中子 - 涡旋速度成比例的纵向力。与电子贡献不同，该力没有横向分量，并且在没有中子 - 质子费米液体相互作用时消失。在一个简单模型中，我们分析了该力的主要性质并对其大小进行了基于物理的估计。
英文摘要
We investigate the forces acting on a proton vortex in superconducting neutron-star matter composed of neutrons, protons, and electrons, accounting for Fermi-liquid interactions in the neutron-proton subsystem. While the force arising from electron scattering by the vortex magnetic field is well known, we demonstrate that normal neutrons also exert a force on proton vortices due to Fermi-liquid coupling with superconducting protons. Using a kinetic approach based on Landau Fermi-liquid theory, we show that neutron quasiparticles scatter off a proton vortex through the spatially varying condensate momentum, giving rise to a longitudinal force proportional to the relative neutron-vortex velocity. In contrast to the electron contribution, this force has no transverse component and vanishes in the absence of neutron-proton Fermi-liquid interaction. Within a simple model, we analyze the main properties of this force and provide physically motivated estimates of its magnitude.
