Path integral techniques transfer

Finally, we note that quantum mechanical tunneling effects may also be incorporated through the use of path integral techniques [14]. These effects are believed to be important in electron transfer processes in condensed phases and proteins [15-16]. 

Because the path integral techniques can account for quantum effect directly in the simulations, the methodology has been used mostly in studies of the behavior of quantum solutes, including tunneling, charge transfer between solutes, and hydrated electrons. Simulations of pure water ° investigated quantum corrections to effective potentials. The Feynman-Hibbs effective potential is a computationally simple method for estimating quantum effects and has been used to examine the differences in the properties of H2O and 02 . ...
