Instanton rate theory is used to study tunneling events in a wide range of systems including low-temperature chemical reactions. Despite many successful applications, the method has never been obtained from first principles, relying instead on the "ImF" premise. In this paper, the same expression for the rate of barrier penetration at finite temperature is rederived from quantum scattering theory [W. H. Miller, S. D. Schwartz, and J. W. Tromp, J. Chem. Phys. 79, 4889 (1983)] using a semiclassical Green's function formalism. This justifies the instanton approach and provides a route to deriving the rate of other processes.

    quant-ph 2025-06 conditional novelty 7.0 of 10

    A corrected nonadiabatic instanton rate theory, n-ImF, subtracts the zero-hop term to recover both the Born-Oppenheimer and golden-rule limits in deep tunnelling.
