Critical collapse of a self-interacting scalar field in asymptotically anti-de Sitter spacetime
Li-Jie Xin, Xiangdong Zhang
We study the critical gravitational collapse of a spherically symmetric massless scalar field in asymptotically anti-de Sitter (AdS) spacetime. The scalar field potential adopted h…

Critical collapse of a massive scalar field in semi-classical loop quantum gravity
Li-Jie Xin, Xiangdong Zhang
We investigate critical phenomena during the gravitational collapse of a massive scalar field under two distinct semi-classical loop quantum gravity (LQG) approaches within spheric…

Energy transfer in the collision of two scalar wave packets in spherical symmetry
Li-Jie Xin, Jun-Qi Guo, Cheng-Gang Shao
We study the collisions of two scalar wave packets in the asymptotically flat spacetime and asymptotically anti-de Sitter spacetime in spherical symmetry. An energy transfer formul…
