The time-dependent geometrical separatrices governing state transitions in field-induced
ketene isomerization are constructed using the method of Lagrangian descriptors. We obtain …

Dynamics between reactants and products are often mediated by a rate-determining barrier
and an associated dividing surface leading to the transition state theory rate. This framework …

The persistence of a transition state structure in systems driven by time-dependent
environments allows the application of modern reaction rate theories to solution-phase and …

Reaction rates across time-dependent barriers are difficult to define and difficult to obtain
using standard transition state theory approaches because of the complexity of the geometry …

The framework of transition state theory relies on the determination of a geometric structure
identifying reactivity. It replaces the laborious exercise of following many trajectories for a …

In chemical or physical reaction dynamics, it is essential to distinguish precisely between
reactants and products for all times. This task is especially demanding in time-dependent or …

Classical transition state theory has been extended to address chemical reactions across
barriers that are driven and anharmonic. This resolves a challenge to the naive theory that …

The dynamical characteristics of a region of regular vibrational motion in the sea of chaos
above the saddle point corresponding to the linear C–N–K configuration is examined in …

In chemical reactions, trajectories typically turn from reactants to products when crossing a
dividing surface close to the normally hyperbolic invariant manifold (NHIM) given by the …

We discuss a general useful theoretical framework to study dynamical localization in
ultracold atomic systems confined in periodically shaken optical lattices. Our theory allows to …
