Wiggling boundary and corner edge modes in JT gravity with defects
Kang Liu, Shoupan Liu, Xiao-Mei Kuang
We study the gravitational edge modes (GrEMs) and gauge edge modes (GaEMs) in Jackiw-Teitelboim (JT) gravity on a wiggling boundary. The wiggling effect manifests as a series of sp…

Non-linearly scalarized supermassive black holes
Shoupan Liu, Yunqi Liu, Yan Peng +1
In this study, we investigate a nonlinear mechanism driving the formation of scalarized rotating black holes within a scalar-Gauss-Bonnet gravity framework that includes an additio…

Rotating scalarized supermassive black holes
Shoupan Liu, Yunqi Liu, Yan Peng +1
In this study, we investigate rotating black hole solutions within a scalar Gauss-Bonnet gravity framework that incorporates a squared Gauss-Bonnet term. By employing a quadratic e…
