我们考虑有限温度下多个标量场的自由理论，并研究通过标量场的自由流动定义的诱导几何形状，遵循本作者提出的方法作为 AdS/CFT 对应构造方法的可能候选者。我们发现全息度量具有以下属性：i）它是一种渐近反德西特（AdS）黑膜度量，具有一些未知的物质贡献。 ii）它没有坐标奇点和较温和的曲率奇点。 iii) 其时间分量在某个 AdS 径向切片处呈指数衰减。我们发现物质遍布整个空间，我们推测这是由于无限多个无质量的高自旋场的热激发所致。我们推测以上三者是通过流动方程方法全息实现的黑洞的一般特征。
We consider a free theory of multiple scalar fields at finite temperature and study the induced geometry defined through a free flow of the scalar fields, following the method proposed by the present authors as a possible candidate of the constructive approach for AdS/CFT correspondence. We find that the holographic metric has the following properties: i) It is an asymptotic Anti-de Sitter (AdS) black brane metric with some unknown matter contribution. ii) It has no coordinate singularity and milder curvature singularity. iii) Its time component decays exponentially at a certain AdS radial slice. We find that the matter spreads all over the space, which we speculate to be due to thermal excitation of infinitely many massless higher spin fields. We conjecture that the above three are generic features of a black hole holographically realized by the flow equation method.
