论文摘要
在本文中，我们研究了黑孔和标量在爱因斯坦重力中的特性，当它最小化与标量场$ ϕ $，并具有不对称的势$ V（ϕ）$，该$（ϕ）$。几十年前，Rev. d \ textbf {73}（2006），084002]。 $ v（ϕ）$已在宇宙学中应用，以描述从虚假真空到真空真空的量子隧道过程，并包含局部最大值，局部最小值（假真空）和全球最小值（真真空）。特别是我们专注于渐近平面解决方案，可以通过适当地固定$ v $的本地最低限度来构建。 Schwarzschild Black Hole出现了毛茸茸的黑洞溶液的一个分支，我们研究了这种构型的存在的领域。它们可以在小范围极限（即标量）中到达类似粒子的溶液。我们研究黑洞和标量的稳定性，表明它们在径向扰动下都是不稳定的。
In this paper we study the properties of black holes and scalarons in Einstein gravity when it is minimally coupled to a scalar field $ϕ$ with an asymmetric potential $V(ϕ)$, constructed in [Phys. Rev. D \textbf{73} (2006), 084002] a few decades ago. $V(ϕ)$ has been applied in the cosmology to describe the quantum tunneling process from the false vacuum to the true vacuum and contains a local maximum, a local minimum (false vacuum) and a global minimum (true vacuum). In particular we focus on the asymptotically flat solutions, which can be constructed by fixing appropriately the local minimum of $V$. A branch of hairy black holes solutions emerge from the Schwarzschild black hole, and we study the domain of existence of such configurations. They can reach to a particle-like solution in the small horizon limit, i.e. the scalarons. We study the stability of black holes and scalarons, showing that all of them are unstable under radial perturbations.
