Neural network approach to time-dependent dividing surfaces in classical reaction dynamics
Philippe Schraft, Andrej Junginger, Matthias Feldmaier +4
In a dynamical system, the transition between reactants and products is typically mediated by an energy barrier whose properties determine the corresponding pathways and rates. The…
Ensemble Methods as a Defense to Adversarial Perturbations Against Deep Neural Networks
Thilo Strauss, Markus Hanselmann, Andrej Junginger +1
Deep learning has become the state of the art approach in many machine learning problems such as classification. It has recently been shown that deep learning is highly vulnerable…
Chemical dynamics between wells across a time-dependent barrier: Self-similarity in the Lagrangian descriptor and reactive basins
Andrej Junginger, Lennart Duvenbeck, Matthias Feldmaier +3
In chemical or physical reaction dynamics, it is essential to distinguish precisely between reactants and products for all time. This task is especially demanding in time-dependent…
Obtaining time-dependent multi-dimensional dividing surfaces using Lagrangian descriptors
Matthias Feldmaier, Andrej Junginger, Jörg Main +2
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 framew…
Variational principle for the determination of unstable periodic orbits and instanton trajectories at saddle points
Andrej Junginger, Jörg Main, Günter Wunner +1
The complexity of arbitrary dynamical systems and chemical reactions, in particular, can often be resolved if only the appropriate periodic orbit - in the form of a limit cycle, di…
