AI中文摘要：
我们研究了向列 aerogel 中超流 3He 的极性相对由磁性杂质散射诱导的微扰的稳定性。我们表明，当该微扰同时破坏轴向对称性和时间反演对称性时，极性畸变的 A 相会以最高的转变温度实现。在提出的 p 波散射势模型（该模型考虑了散射准粒子的轨道角动量与散射体的磁矩结构之间的有效自旋-轨道相互作用）中，我们求解了 Gor'kov 自洽方程的本征值与本征向量问题。最后，我们讨论了我们的结果如何与现有实验数据相关联。
英文摘要：
We study the stability of the solution corresponding to the polar phase of superfluid 3He in nematic aerogels with respect to perturbations induced by magnetic impurity scattering. We show that when the perturbation simultaneously breaks axial and time-reversal symmetry, the polar-distorted A phase is realized with the highest transition temperature. Within the proposed model of a p-wave scattering potential, which accounts for the effective spin-orbit interaction between the orbital angular momentum of a scattering quasiparticle and the magnetic moment texture of the scatterer, we solve the eigenvalue and eigenvector problem for the Gor'kov self-consistency equation. Finally, we discuss how our results relate to the available experimental data.
