标题： Analytical Holographic Superconductor with Backreaction Using AdS3/CFT2

摘要： 全息模型用于二维超导体，这是通过考虑体内的三维引力来研究的。 为了找到临界温度，我们使用了斯特姆-利乌维尔变分法。 而同样的方法被用于计算边界上对偶算符的凝聚。 我们通过将场的微扰方法与小参数相结合，然后在运动方程上应用变分积分，从而在度规中包含了反作用。 成功地获得了考虑反作用效应的临界温度，并且我们表明，随着场的反作用增加，临界温度会下降，并且使凝聚变得更困难。 我们可以用我们的分析结果来支持之前报告的数值数据。 显示英文摘要

摘要： The holographic model for a two-dimensional superconductor has been investigated by considering the three-dimensional gravity in the bulk. To find the critical temperature, we used the Sturm-Liouville variational method. Where as the same method is applied for calculating the condensation of the dual operators on the boundary. We included the back reactions on the metric by a combination of the perturbation method of the fields with respect to the small parameter and then applying the variational integrals on the resulting equations of the motion. The critical temperature has been successfully obtained on the backreaction effects, and we showed that it dropped with a rise in the backreaction of the fields, and it makes the condensation harder. We can use our analytical results to support the numerical data which was reported previously.
