摘要

In Chap. 3 , we followed the practical workflow of the diffusion Monte Carlo (DMC) method while introducing its conceptual background. The central idea of the method lies in the equivalence between the “time evolution of particle density via random walk governed by the Langevin equation” and the “time evolution of the density function via the Fokker-Planck equation” (Sect. 3.2.2 ).
