全息超导体是全息术的一个重要竞技场,因为它允许具体的计算来进一步理解体物理和边界物理之间的字典。最近人们感兴趣的一个重要量是全息复杂性。有关全息复杂性在相变过程中的行为的文献中已经提出了明确的要求。我们通过对一维全息超导体的数值研究来澄清这个问题。我们的研究表明,全息复杂性并不表现出与全息纠缠熵相同的方式。然而,这两个量的普适项是有限的,反映了在相同的临界温度下的相变。
Holographic superconductor is an important arena for holography, as it allows concrete calculations to further understand the dictionary between bulk physics and boundary physics. An important quantity of recent interest is the holographic complexity. Conflicting claims had been made in the literature concerning the behavior of holographic complexity during phase transition. We clarify this issue by performing a numerical study on one-dimensional holographic superconductor. Our investigation shows that holographic complexity does not behave in the same way as holographic entanglement entropy. Nevertheless, the universal terms of both quantities are finite and reflect the phase transition at the same critical temperature.
