This work demonstrates decoherence of inequivalent Hamiltonians in a de Sitter environment, suggesting inflation influences physical laws.
This work explores a minimal, analytically tractable model in which inequivalent Hamiltonians—representing different possible “laws of physics”—interact with a de Sitter environment and undergo rapid decoherence during inflation. The model demonstrates that interference between law sectors is suppressed on a timescale τ_d ~ 1/((Δg)^2 H), suggesting that inflation enforces classicality not only on states but on dynamical rules themselves.
