WebFirst passage time Markov chain analysis 583 Nucleation theory can be applied to the double kink problem to obtain the effective width of the saddle point and hence the width of a stable double kink. Let us deﬁne w as the distance beyond w∗ where the free energy of the double kink is F ∗ −kT, where kT is the thermal energy. WebOct 21, 2024 · Most of the time they tend to be the same, but for example the first passage time through a boundary can potentially be different from the first hitting time of that boundary if it's possible to pass through the boundary without ever hitting it.
