自旋1色超导体的对称性破缺和集体模

Symmetry breaking patterns and collective modes of spin-one color superconductors

Tomas Brauner, Jin-yi Pang, Qun Wang

摘要:

自旋一色超导体是致密恒星内部致密物质的一个可行的候选相。它的低能激发将影响这类物质的输运性质,从而影响中子星的后期演化。它也提供了一个很好的自发对称性破缺的例子,具有丰富的破缺模式。本文重新分析了自旋为1的色超导体的相图,指出其中有一部分被非惰性态所占据,这是迄今文献中所忽略的。我们分类集体Nambu-Goldstone模式,这是必不可少的运输现象。

英文摘要:

Spin-one color superconductor is a viable candidate phase of dense matter in the interiors of compact stars. Its low-energy excitations will influence the transport properties of such matter and thus have impact on late-stage evolution of neutron stars. It also provides a good example of spontaneous symmetry breaking with rich breaking patterns. In this contribution, we reanalyze the phase diagram of a spin-one color superconductor and point out that a part of it is occupied by noninert states, which have been neglected in literature so far. We classify the collective Nambu--Goldstone modes, which are essential to the transport phenomena.
