标题： Diving into a holographic multi-band superconductor

摘要： 在这项工作中，我们研究了全息双带超导体模型的内部结构。我们着重于具有两个标量场的全息超导系统，这两个标量场对应于对偶凝聚态系统中的两个s波序参量。我们发现了一种新的过渡规则，它发生在黑洞奇点附近的Kasner宇宙中，这种规则与全息单带超导体模型不同。这一过渡规则是对Kasner过渡行为到涉及多个自由参数场景的一般化推广，对于揭示毛发黑洞的最普遍内部结构非常有用。此外，我们发现Kasner指数对边界系统序参量的细节敏感。我们所发现的不同近奇点结构表明黑洞内部在表征边界对偶凝聚态系统中起着关键作用。 显示英文摘要

摘要： In this work, we investigate the interior structure of a holographic multi-band superconductor model. We focus on the holographic superconductor system with two scalar fields which correspond to two s-wave order parameters in the dual condensed matter system. We discover a new kind of transition rule among Kasner universe near the black hole singularity which is distinct from the holographic single-band superconductor model. This transition rule is the first generalization of Kasner transition behavior to scenarios involving multiple free parameters, which is useful for uncovering the most general interior structures of hairy black holes. Moreover, we find that the Kasner exponents are sensitive to the details of order parameters in boundary system. These different near singularity structures we found show that the black hole interior plays crucial role in characterizing the boundary dual condensed matter systems.
