Quantum entanglement in de Sitter space with a wall, and the decoherence of bubble universes
Andreas Albrecht, Sugumi Kanno, Misao Sasaki
We study the effect of a bubble wall on the entanglement entropy of a free massive scalar field between two causally disconnected open charts in de Sitter space. We assume there is…
