旋转致密夸克物质中非阿贝尔涡旋的自发磁化
Spontaneous Magnetization through Non-Abelian Vortex Formation in Rotating Dense Quark Matter
摘要：
当高密度QCD色超导体旋转时，沿旋转轴不可避免地产生超流涡旋。在渐近大化学势下实现的色香味锁相中，出现了携带超流环流和色磁通量的非阿贝尔涡旋。一个家庭的解决方案有一个退化的特点是Nambu-Goldtone模式CP 2，与色味锁定对称性自发打破附近的旋涡。本文研究了非阿贝尔涡旋的电磁耦合问题，发现引入有效势可以消除涡旋的简并性。我们得到了一个稳定的涡旋解和一族亚稳定的涡旋解，这两个解除了携带色磁通量外，还携带普通的磁通量。讨论了亚稳涡旋的量子力学衰变，并将有效势与其它已知势、量子力学诱导势和奇异夸克质量诱导势进行了比较.
英文摘要：
When a color superconductor of high density QCD is rotating, superfluid vortices are inevitably created along the rotation axis. In the color-flavor locked phase realized at the asymptotically large chemical potential, there appear non-Abelian vortices carrying both circulations of superfluid and color magnetic fluxes. A family of solutions has a degeneracy characterized by the Nambu-Goldtone modes CP2, associated with the color-flavor locked symmetry spontaneously broken in the vicinity of the vortex. In this paper, we study electromagnetic coupling of the non-Abelian vortices and find that the degeneracy is removed with the induced effective potential. We obtain one stable vortex solution and a family of metastable vortex solutions, both of which carry ordinary magnetic fluxes in addition to color magnetic fluxes. We discuss quantum mechanical decay of the metastable vortices by quantum tunneling, and compare the effective potential with the other known potentials, the quantum mechanically induced potential and the potential induced by the strange quark mass.
