Generalized Langevin Theory of a Biomolecule-in-Water System
摘要
In Chap. 3 , we have derived a generalized Langevin equation for a system of pure water, that describes the temporal as well as spatial density fluctuation of in water [(Eq. 3.84 ) in Chap. 3]. The most important finding there is that the temporal density fluctuation is harmonic, or Gaussian. The Gaussian character has a great advantage for a theoretical treatment, since it allows a harmonic analysis of the fluctuation.
