A new CERN paper extends the F-theorem — a deep law about how physical complexity must decrease as you zoom out — into the curved geometry of Anti-de Sitter space, potentially reshaping our understanding of quantum field theory's structure.

Theory Briefing
- CERN researchers introduce a regularized free energy for massive quantum field theories living in Anti-de Sitter (AdS) curved space.
- The F-theorem states that a quantity called free energy must decrease along renormalization group flows, acting like an arrow of time for physical theories.
- Extending this theorem to AdS geometry tests whether fundamental irreversibility principles survive in the curved spacetimes central to string theory and holography.
