论文摘要
全息超导体是超导性的全息双重双重双重双重导向，但是在标准全息超导体中没有Meissner效应。这是因为边界麦克斯韦字段是作为外部源添加的，并且不是动态的。我们通过将半经典的麦克斯韦方程施加在广告边界上，从而在分析上显示了Meissner效应。与金茨堡 - 兰道（GL）理论不同，即使在$ e \ to \ infty $限制中，极端的I限制也无法达到，其中$ e $是$ u（1）$ u（1）。这是由于即使在纯粹的Maxwell理论中存在的界流。在批量的5维情况下，GL参数和双GL理论是根据缩放维度2的顺序参数分析获得的。
The holographic superconductor is the holographic dual of superconductivity, but there is no Meissner effect in the standard holographic superconductor. This is because the boundary Maxwell field is added as an external source and is not dynamical. We show the Meissner effect analytically by imposing the semiclassical Maxwell equation on the AdS boundary. Unlike in the Ginzburg-Landau (GL) theory, the extreme Type I limit cannot be reached even in the $e\to\infty$ limit where $e$ is the $U(1)$ coupling of the boundary Maxwell field. This is due to the bound current which is present even in the pure bulk Maxwell theory. In the bulk 5-dimensional case, the GL parameter and the dual GL theory are obtained analytically for the order parameter of scaling dimension 2.
