论文摘要
我们在软壁调节的抗de-sitter Einstein-Maxwell-Dirac理论中构建一个完全量子零温度的电子星，与Reissner-Nordström黑洞相比，它在热力学上是稳定的。软壁仅作用于费米子自由度的有效质量上，并允许进行完全反反应的解决方案。恒星在RG流动上是全息双重的，其中含量的费米液体开始从UV CFT中出现，但是一旦有效的能量尺度低于费米金自由度的间隙，又有紫外线液体。然后，RG流返回到具有全息偶的相对论固定点的非平凡的相对论固定点。因此，我们的调节量子电子星是Horowitz-Roberts-Gubser-rocha-rocha广告 - 到ads域壁溶液的费米子类似物，用于全息超导体。
We construct a fully quantum zero-temperature electron star in a soft-wall regulated anti-de-Sitter Einstein-Maxwell-Dirac theory that is thermodynamically stable compared to the Reissner-Nordström black hole. The soft wall only acts on the effective mass of the fermionic degrees of freedom, and allows for a controlled fully backreacted solution. The star is holographically dual to an RG flow where a gapped Fermi liquid starts to emerge from a UV CFT, but decouples again once the effective energy scale becomes lower than the the gap of the fermionic degrees of freedom. The RG flow then returns to a non-trivial strongly coupled relativistic fixed point with a holographic dual. Our regulated quantum electron star is thus the fermionic analogue of the Horowitz-Roberts-Gubser-Rocha AdS-to-AdS domain wall solution for the holographic superconductor.
