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 formula is obtained, $y=Cm_{i}m_{o}/r$, where $y$ is the
transferred energy in the collisions of the two wave packets, $m_i$ and $m_o$
are the Misner-Sharp energies for the ingoing and outgoing wave packets,
respectively, $r$ is the areal radius and collision place, and $C=1.873$ and
$C=1.875$ for the asymptotically flat spacetime and asymptotically anti-de
Sitter spacetime circumstances, respectively. The formula is universal,
independent of the initial profiles of the scalar fields.
The study examines the collisions of two scalar wave packets in both asymptotically flat spacetime and asymptotically anti-de Sitter spacetime in spherical symmetry. The researchers derived an energy transfer formula, which states that the transferred energy, y, in the collisions of the two wave packets is given by y = Cmimo/r, where mi and mo are the Misner-Sharp energies for the ingoing and outgoing wave packets, r is the areal radius and collision place, and C has different values based on the spacetime circumstances – C=1.873 for asymptotically flat spacetime and C=1.875 for asymptotically anti-de Sitter spacetime. Notably, the formula is universal and independent of the initial profiles of the scalar fields.
