自旋为0的超流体中的涡旋携带磁通量

Vortices in spin-0 superfluids carry magnetic flux

Aleksey Cherman, Theodore Jacobson, Srimoyee Sen, Laurence G. Yaffe

摘要:

自旋$0$超流体中的涡旋一般在其核心内携带磁场,因此即使是中性超流体涡旋也可以被认为是磁通量管。我们给出了一个系统的分析,这种“涡流磁效应”使用有效场论,澄清早期文献的主题。我们的分析表明,在超流氦- $4$中,涡旋磁效应可能大到足以在实验上检测到。

英文摘要:

Vortices in spin-$0$ superfluids generically carry magnetic fields inside their cores, so that even neutral superfluid vortices may be thought of as magnetic flux tubes. We give a systematic analysis of this `vortex magnetic effect' using effective field theory, clarifying earlier literature on the subject. Our analysis shows that in superfluid Helium-$4$ the vortex magnetic effect may be large enough to be experimentally detectable.
