Dissipative tunneling rates through the incorporation of first-principles electronic friction in instanton rate theory. II. Benchmarks and applications

Dissipative tunneling rates through the incorporation of first-principles electronic friction in instanton rate theory. II. Benchmarks and applications

Y. Litman, E. S. Pos, C. L. Box, R. Martinazzo, R. J. Maurer, M. Rossi J. Chem. Phys. 156, 194107 (2022)

"Hydrogen chemistry at surfaces can involve nonadiabatic effects (NAEs) and quantum nuclear effects (NQEs). The theoretical modeling of such reactions presents a formidable challenge for theory. In this work, we derive a theoretical framework that captures both NQEs and NAEs and, due to its high efficiency, can be applied to first-principles calculations of reaction rates in high-dimensional realistic systems. More specifically, we develop a method that we coin ring polymer instanton with explicit friction, starting from the ring polymer instanton formalism applied to a system–bath model. In this second part, we present benchmark calculations and applications."
