论文摘要
先前的研究表明,在具有简单且动机的自我交互潜力的情况下,渐近平坦和球形黑洞可以在爱因斯坦 - 马克斯韦尔重力中携带最小耦合和带电的标量云/头发。我们将这些研究扩展到爱因斯坦出生的污染重力,以考虑电磁场非线性的影响。一系列的球形云/毛茸茸的黑洞解决方案是数值构建的。结果表明,增加出生的粉红色耦合常数$ b $将使解决方案存在的范围缩小,甚至在$ b $足够大时消失。这意味着,与重力竞争,电磁场的非线性将使标量云/头发的形成更加困难甚至不可能。
Previous studies showed that, in the presence of a simple and well-motivated self-interaction scalar potential, asymptotically flat and spherical black holes can carry minimally coupled and charged scalar cloud/hair in Einstein-Maxwell gravity. We extend these studies to Einstein-Born-Infeld gravity to consider the effect of nonlinearity of the electromagnetic field. Series of spherical cloudy/hairy black hole solutions are constructed numerically. Results show that increasing the Born-Infeld coupling constant $b$ will make the domain of existence of the solution shrink or even disappear when $b$ is large enough. This implies that, competing with the gravitation, nonlinearity of the electromagnetic field will make the formation of scalar cloud/hair harder or even impossible.
