摘要

We argue that the validity of the WKB approach for calculating nonequilibrium properties of a nonlinear stochastic system requires an additional criterion involving the time interval, compared with the standard WKB criterion considered by Mannella [R. Mannella, Phys. Rev. E 58,2479 (1999)]. In order to clarify the situation, we compare the WKB solution with the direct numerical solution of the Fokker-Plank equation. [References: 2]
