Controlling reaction dynamics in chemical model systems through external driving
Johannes Reiff, Robin Bardakcioglu, Matthias Feldmaier +2
The rate of a chemical reaction can often be determined by the properties of a rank-1 saddle and the associated transition state separating reactants and products. We have found ev…
Dynamics and decay rates of a time-dependent two-saddle system
Johannes Reiff, Matthias Feldmaier, Jörg Main +1
The framework of transition state theory (TST) provides a powerful way for analyzing the dynamics of physical and chemical reactions. While TST has already been successfully used t…
Thermal decay rates of an activated complex in a driven model chemical reaction
Robin Bardakcioglu, Johannes Reiff, Matthias Feldmaier +2
Recent work has shown that in a non-thermal, multidimensional system, the trajectories in the activated complex possess different instantaneous and time-averaged reactant decay rat…
Influence of external driving on decays in the geometry of the LiCN isomerization
Matthias Feldmaier, Johannes Reiff, Rosa M Benito +3
The framework of transition state theory relies on the determination of a geometric structure identifying reactivity. It replaces the laborious exercise of following many trajector…
Neural network approach for the dynamics on the normally hyperbolic invariant manifold of periodically driven systems
Martin Tschöpe, Matthias Feldmaier, Jörg Main +1
Chemical reactions in multidimensional systems are often described by a rank-1 saddle, whose stable and unstable manifolds intersect in the normally hyperbolic invariant manifold (…
Phase-space resolved rates in driven multidimensional chemical reactions
Matthias Feldmaier, Robin Bardakcioglu, Johannes Reiff +2
Chemical reactions in multidimensional driven systems are typically described by a time-dependent rank-1 saddle associated with one reaction and several orthogonal coordinates (inc…
Invariant Manifolds and Rate Constants in Driven Chemical Reactions
Matthias Feldmaier, Philippe Schraft, Robin Bardakcioglu +7
Reaction rates of chemical reactions under nonequilibrium conditions can be determined through the construction of the normally hyperbolic invariant manifold (NHIM) [and moving div…
Binary contraction method for the construction of time-dependent dividing surfaces in driven chemical reactions
Robin Hobil Bardakcioglu, Andrej Junginger, Matthias Feldmaier +2
Transition state theory formally provides a simplifying approach for determining chemical reaction rates and pathways. Given an underlying potential energy surface for a reactive s…
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…
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…
Impact of the valence band structure of CuO on excitonic spectra
Frank Schweiner, Jörg Main, Matthias Feldmaier +2
We present a method to calculate the exciton spectra of all direct semiconductors with a complex valence band structure. The Schrödinger equation is solved using a complete basis s…
Rydberg systems in parallel electric and magnetic fields: an improved method for finding exceptional points
Matthias Feldmaier, Jörg Main, Frank Schweiner +2
Exceptional points are special parameter points in spectra of open quantum systems, at which resonance energies degenerate and the associated eigenvectors coalesce. Typical example…
