Nonadiabatic Forward-Flux Sampling of Rare Molecular Gas-Phase Ammonia Photodissociation

Madlen Maria Reiner, Johannes C. B. Dietschreit, Leticia González +1

Simulating rare events in photochemistry by brute-force surface hopping is computationally prohibitive: most propagated trajectories either remain nonreactive or follow dominant re…

Reweighting free energy profiles between universal machine learning interatomic potentials for fast consensus building

Sauradeep Majumdar, Miguel Steiner, Johannes C. B. Dietschreit +4

Free energy profiles serve as a fundamental bridge between microscopic atomic fluctuations and macroscopic thermodynamic observables. Estimating the free energy profile along a rea…

NATPS: Nonadiabatic Transition Path Sampling Using Time-Reversible MASH Dynamics

Xiran Yang, Madlen Maria Reiner, Brigitta Bachmair +3

Rare nonadiabatic events play a central role in photochemistry but remain difficult to simulate because excited-state dynamics is computationally demanding and often stochastic. He…

The Entropic Barrier around the Conical Intersection Seam

Johannes C. B. Dietschreit, Sebastian Mai, Leticia González

Conical intersections (CIs) are seen as the main mediators of nonadiabatic transitions; yet, mixed quantum-classical (MQC) simulations that treat nuclei as classical point particle…

Single-model uncertainty quantification in neural network potentials does not consistently outperform model ensembles

Aik Rui Tan, Shingo Urata, Samuel Goldman +2

Neural networks (NNs) often assign high confidence to their predictions, even for points far out-of-distribution, making uncertainty quantification (UQ) a challenge. When they are…

Entropy and Energy Profiles of Chemical Reactions

Johannes C. B. Dietschreit, Dennis J. Diestler, Rafael Gómez-Bombarelli

The description of chemical processes at the molecular level is often facilitated by use of reaction coordinates, or collective variables (CVs). The CV measures the progress of the…

Differentiable Simulations for Enhanced Sampling of Rare Events

Martin Šípka, Johannes C. B. Dietschreit, Lukáš Grajciar +1

Simulating rare events, such as the transformation of a reactant into a product in a chemical reaction typically requires enhanced sampling techniques that rely on heuristically ch…
