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…

Energy in critical collapse
Yu Hu, Jun-Qi Guo, Junbin Li +2
We study the energy issue in critical collapse of a spherically symmetric scalar field. It is found that in critical collapse, the contribution from the material energy is greater…
