Early-Time Nonlinear Growth in an Unstable Q-Ball Hairy Black Hole
Lang Cheng, Guangzhou Guo, Peng Wang +1
Early-time evolution away from an unstable equilibrium in a nonlinear system is often expected to be governed by the associated linear instability. Combining full nonlinear evoluti…
Spin-induced Scalarized Black Holes in Einstein-Maxwell-scalar Models
Lang Cheng, Guangzhou Guo, Peng Wang +1
We construct spin-induced scalarized black hole solutions in a class of Einstein-Maxwell-scalar models, where a scalar field is non-minimally coupled to the electromagnetic field.…
Fixing the AdS metric from the pure state entanglement entropies of CFT
Peng Wang, Houwen Wu, Haitang Yang
In this paper, based on RT formula, by identifying the pure state UV and IR entanglement entropies of a perturbed CFT with geodesic lengths in the bulk, we demonstrate that the…
Fixing three dimensional geometries from entanglement entropies of CFT
Peng Wang, Houwen Wu, Haitang Yang
In this paper, we propose a method of fixing the leading behaviors of three dimensional geometries from the dual CFT entanglement entropies. We employ only the holographic prin…
Spin-induced Scalar Clouds around Kerr-Newman Black Holes
Guangzhou Guo, Peng Wang, Tianshu Wu +1
Recent studies have demonstrated that a scalar field non-minimally coupled to the electromagnetic field can experience a spin-induced tachyonic instability near Kerr-Newman black h…
