作为刚性弦的中心涡

Center vortices as rigid strings

P. V. Buividovich, M. I. Polikarpov

摘要:

结果表明,在SU(2)格点规范理论中,中心涡旋的作用量与涡旋表面的外曲率和内曲率有很强的相关性,并且这种相关性在连续极限下仍然存在。因此,有效涡作用的一个很好的近似是刚性弦的作用,它可以再现中心涡的一些观察到的几何性质。它是澄清,刚性可能会引起一些领域的本地化涡,并进行了独立的模型本地化测试。在阿贝尔投影中检测到的单极被讨论为这样的二维领域的自然候选人。

英文摘要:

It is shown that the action associated with center vortices in SU(2) lattice gauge theory is strongly correlated with extrinsic and internal curvatures of the vortex surface and that this correlation persists in the continuum limit. Thus a good approximation for the effective vortex action is the action of rigid strings, which can reproduce some of the observed geometric properties of center vortices. It is conjectured that rigidity may be induced by some fields localized on vortices, and a model-independent test of localization is performed. Monopoles detected in the Abelian projection are discussed as natural candidates for such two-dimensional fields.
