论文摘要
我们研究了从标量场的耦合到Einstein张量的二维广告Black Hole的背景，我们研究了反应全息超导体的性能。在没有Neumann边界条件的情况下施加试验功能的Dirichlet边界条件，我们采用迭代程序来改善分析性Sturm-Liouville方法，以探索Einstein Tensor对全息超导剂的纯粹效应，并发现Einstein Tensor Hinders Hinders Hinders scalar Field的冷凝物，但不会影响关键现象。我们的分析结果与“边缘稳定模式”方法的数值结果非常吻合，这意味着Sturm-Liouville方法仍然很强大，可以研究从标量场到Einstein Tensor的耦合中的全息超导体，即使我们考虑了逆向。
We investigate the properties of the backreacting holographic superconductors from the coupling of a scalar field to the Einstein tensor in the background of a d-dimensional AdS black hole. Imposing the Dirichlet boundary condition of the trial function without the Neumann boundary conditions, we improve the analytical Sturm-Liouville method with an iterative procedure to explore the pure effect of the Einstein tensor on the holographic superconductors and find that the Einstein tensor hinders the condensate of the scalar field but does not affect the critical phenomena. Our analytical findings are in very good agreement with the numerical results from the "marginally stable modes" method, which implies that the Sturm-Liouville method is still powerful to study the holographic superconductors from the coupling of a scalar field to the Einstein tensor even if we consider the backreactions.
