强卷吸和$Σ^-$超子能隙引起的中子星中强子超流体的非常规转动响应

Unconventional rotational responses of hadronic superfluids in a neutron star caused by strong entrainment and a $Σ^-$ hyperon gap

Egor Babaev

摘要:

我表明,通常的中子星的旋转响应模型,它预测旋转引起的中子涡旋和没有旋转引起的质子涡旋,不持有(i)超过一定阈值的夹带相互作用强度,也不(ii)在非零的情况下$Σ^-$超子间隙。我证明,在这两种情况下的旋转响应涉及创建相绕组在带电冷凝。由这些效应引起的涡旋的束缚态晶格可以(对于一系列参数)强烈地减少旋转诱导的涡旋与携带超导组件的磁场之间的相互作用。

英文摘要:

I show that the usual model of the rotational response of a neutron star, which predicts rotation-induced neutronic vortices and no rotation-induced protonic vortices, does not hold (i) beyond a certain threshold of entrainment interaction strength nor (ii) in case of nonzero $Σ^-$ hyperon gap. I demonstrate that in both these cases the rotational response involves creation of phase windings in electrically charged condensate. Lattices of bound states of vortices which are caused these effects can (for a range of parameters) strongly reduce the interaction between rotation-induced vortices with magnetic-field carrying superconducting components.
