报告摘要:

Spontaneous scalarization is a mechanism that endows black holes with scalar hair only when a specific field exceeds a threshold, thereby allowing them to evade weak-field tests. In this talk, I will explore rotating scalar clouds and scalarized black holes within the framework of Einstein-Maxwell-Scalar models. These models can exhibit a tachyonic instability due to non-minimal couplings between the scalar and electromagnetic fields, which may lead to the condensation of the scalar field around black holes. It is noteworthy that scalarized black holes have been shown to possess stable light rings. I will also address the nonlinear (in)stability of these stable light rings within this context.
