Perspective explores Fermi's golden rule applications in chemical physics, clarifying ambiguities and generalizations.
This perspective provides a succinct history of Fermi's golden rule (FGR), an overview of its derivation, assumptions, and representative forms. Major applications of FGR, mostly in the field of chemical physics, are reviewed. These illustrate the broad applicability and success of FGR. Ambiguities and open issues encountered in practical applications of FGR are clarified. Recent advances in generalizations of FGR and computational methods for practical applications are addressed.
