Ring-polymer instanton theories offer a very promising approach to solve this problem, since they can be rigorously derived using semiclassical approximations and can capture nuclear quantum effects such as tunnelling and zero-point energy at a cost similar to that of a classical calculation. A successful instanton rate theory already exists within the Born--Oppenheimer approximation, for which the optimal","authors_text":"Jeremy O. Richardson, Joseph E. Lawrence, Rhiannon A.
