Abstract

It is proved that in the polar phase of superfluid 3He stabilized by a nematic aerogel the temperature dependence of the gap in the spectrum of Fermi excitations must be the same as that in the bulk polar phase without foreign impurities when the liquid quasiparticles are specularly reflected from the aerogel strands. The analogy with the Anderson theorem for conventional superconductors is discussed.

摘要

证明了在由向列气凝胶稳定的超流体3 He的极性相中,费米激发谱中的间隙的温度依赖性必须与镜面反射液体准粒子时没有外来杂质的本体极性相的温度依赖性相同。从气凝胶丝。讨论了与常规超导体的安德森定理的类比。
