This study from SISSA and Syracuse University demonstrates how environmental decoherence acts as a stabilizing force in cosmological spacetimes by suppressing quantum tunneling between vacua. The research identifies this mechanism as a manifestation of the quantum Zeno effect, where interactions with spectator fields effectively "lock" lighter quantum fields into their local energy minima. These findings advance our understanding of how environmental monitoring prevents unwanted transitions in false vacuum states within the early universe.

Decoherence suppresses quantum tunneling in universe study

Quantum ZeitgeistSeptember 30, 20263 min read

New research from SISSA details how decoherence, a process of environmental interaction, prevents quantum tunneling and stabilizes the universe, according to a study published September 25, 2026.

Researchers at the University of Portsmouth and Syracuse University investigate how quantum decoherence influences the tunneling dynamics of quantum fields in cosmological spacetimes. The study, published in the September 2026 issue of the Journal of Cosmology and Astroparticle Physics, finds that while decoherence is essential for suppressing quantum interference between vacua, its impact on…
