Complex paths for real stochastic processes
D. A. Baldwin, A. J. McKane, S. P. Fitzgerald
The calculation of the decay rate of a metastable state in the path-integral formulation of stochastic processes is revisited. Previous derivations of this rate were achieved at th…

Nonequilibrium statistics of barrier crossings with competing pathways
Gulzar Ahmad, Sergey Saveliev, Steven P Fitzgerald +2
Many biological, chemical, and physical systems are underpinned by stochastic transitions between equilibrium states in a potential energy. Here, we consider such transitions in a…

Timescales for stochastic barrier crossing: inferring the potential from nonequilibrium data
A. J. Archer, T. Ala-Nissila, T. J. W. Honour +1
Kramers' rate theory forms a cornerstone for thermally activated barrier crossing. However, its reliance on equilibrium quantities excludes analysis of nonequilibrium dynamics at e…
