Cover Story: Constructing accurate Potential Energy Surfaces (PESs) is essential in molecular modeling as they govern nuclear forces and enable reliable quantum-dynamics simulations. Ab initio methods provide highly accurate surfaces but are computationally expensive, whereas analytical models are efficient yet too rigid, especially for excited states. Neural networks provide flexible PES approximations but require large datasets. We investigate hybrid residual models that combine physics-based potentials with data-driven corrections. By comparing three hybrid approaches for the ground and first excited states of H₂, we show that they outperform both pure machine learning and pure physics-based models, particularly in low-data regimes.

In Classical Mechanics, time is reversible, i.e., it implies no particular choice: only the observer knows in which direction it flows. The present article re-examines whether this remains true in Quantum Mechanics. In the context of Atomic Physics,...
