Nonadiabatic electron transfer in the condensed phase, via semiclassical and Langevin equation approach
… electron transfer systems. The first method, the semi-classical approximation, is derived from the stationary phase approximation to the path integral in the spin-coherent representation. The resulting equation of motion is a classical-like ordinary differential equation subject to a two-ended …

Effective loop quantization of black holes : a comparative analysis of quantization schemes.
… quantization that is derived from full LQG. The semi-classical approximation of this model resolves the central BH singularity and replaces it with a transition surface. The spacetime to the future of the transition surface depends on the ratio of two spin numbers involved in the model. We also …
