Kramers high-friction barrier-crossing framework: k = (ω_a·ω_b)/(2π·γ)·exp(−E_b/kT) (γ^(−1) Kramers slow-down)

Kramers high-friction escape rate: for a particle in a double-well potential coupled to a heat bath at friction γ, the barrier-crossing rate in the overdamped limit (γ ≫ ω_b) is k = (ω_a·ω_b)/(2π·γ)·exp(−E_b/k_BT), where ω_a is the…
