论文摘要
我们以零密度构建全息超导体。该模型享有一个豪华属性，在分析上可用的背景几何形状双重分析。它在IR中具有高标度的几何形状，在紫外线中是渐近的广告。 IR几何形状的分类为超级解决方案提供了新的见解。我们在数值上构造了毛状黑洞的有限温度解，并通过调整双跟踪变形参数来验证相变。对于来自M理论的全息超导体，我们获得了交流电导率的分析解决方案，该解决方案明确显示了超导的增量功能和硬间隙。
We construct holographic superconductors at zero density. The model enjoys a luxury property that the background geometry dual to the ground state is analytically available. It has a hyperscaling-violating geometry in the IR and is asymptotically AdS in the UV. Classification by IR geometries gives new insights on supergravity solutions. We numerically construct the finite temperature solution of hairy black holes and verify the phase transition by tuning a double-trace deformation parameter. For a holographic superconductor from M-theory, we obtain an analytic solution of the AC conductivity, which explicitly shows a superconducting delta function and a hard gap.
