论文摘要
黑洞自发的标量一直引起越来越多的关注，因为它绕过了众所周知的无头性定理。在这项工作中，我们研究了爱因斯坦 - 斯卡尔 - 高斯 - 邦网理论中的标量，并在具有不同曲率的黑洞背景中具有探针标量场。我们首先在不同的空间中探测黑洞标量的信号。 ADS时空中的标量字段比在平面案例中更容易形成。然后，我们研究了围绕ADS黑洞的标量场，具有负曲率和零曲率。与阴性和零病例相比，ADS Black Hole附近的标量曲率可能更容易出现。在负弯曲情况下，标量场是最难在地平线附近界定的。
Black hole spontaneous scalarization has been attracting more and more attention as it circumvents the well-known no-hair theorems. In this work, we study the scalarization in Einstein-scalar-Gauss-Bonnet theory with a probe scalar field in a black hole background with different curvatures. We first probe the signal of black hole scalarization with positive curvature in different spacetimes. The scalar field in AdS spacetime could be formed easier than that in flat case. Then, we investigate the scalar field around AdS black holes with negative and zero curvatures. Comparing with negative and zero cases, the scalar field near AdS black hole with positive curvature could be much easier to emerge. And in negative curvature case, the scalar field is the most difficult to be bounded near the horizon.
