Abstract This paper studies interacting massive particles on the de Sitter background. It is found that the vacuum acts as an inversely populated medium which is able to generate stimulated radiation. Without back reaction (not considered in this paper) this effect leads to the explosion. It is expected that the proposed “cosmic laser” mechanism depletes the curvature and may help to solve the cosmological constant problem.

- Semiclassical relations and IR effects in de Sitter and slow-roll space-times (2010, background): “For this reason these have been extensively discussed, with arguments ranging from the statement that they can be innocuously eliminated to the statement that they indicate a fundamental instability of de Sitter space causing the cosmological constant to relax to zero [1–7].”
