论文摘要
我们构建了一个描述条纹超导体（SSC）的全息模型，该模型的特征是配对密度波（PDW）。我们明确证明SSC阶段被实现为电荷密度波（CDW）阶和均匀超导（SC）顺序的相互缠绕的阶段。研究了PDW顺序，CDW顺序以及SSC阶段中均匀的SC顺序的接口。发现当CDW顺序和均匀的SC顺序平衡时，PDW顺序是突出的。在存在均匀的SC顺序的情况下，CDW的临界温度变得更高，但其电荷密度幅度被抑制。另一方面，SC顺序对CDW顺序的存在不敏感。我们还证明，在所有可能的解决方案中，SSC相中的黑洞具有最低的自由能，因此受到热力动力学的青睐。
We construct a holographic model describing the striped superconductor (SSC), which is characterized by the presence of pair density waves (PDW). We explicitly demonstrate that the SSC phase is implemented as the intertwined phase of charge density waves (CDW) order and uniform superconducting (SC) order. Theinterplay of PDW order, CDW order as well as the uniform SC order in SSC phase is studied. It is found that the PDW order is prominent when both CDW order and uniform SC order are balanced. The critical temperature of CDW becomes higher in the presence of the uniform SC order, but its charge density amplitude is suppressed. On the other hand, the SC order is not sensitive to the presence of CDW order. We also demonstrate that among all the possible solutions, the black hole in SSC phase has the lowest free energy and thus is thermodynamically favored.
