Concept of interbasin mixing and extension of the Lyapunov exponent in multiple potential-basin dynamics as in structural isomerization of clusters110(1999); http://dx.doi.org/10.1063/1.478191View Description Hide Description
For Hamilton dynamics on a potential that has multiple local basins as in structural isomerizationreaction of clusters, a notion of interbasin mixing is introduced that is responsible for Markov-type stochastic appearance of molecular structures. An extension of the Lyapunov exponent to quantify the time scale to reach interbasin mixing is proposed. The present dynamics also serves as a prototype of multichannel chemical reactions.
