Chiral Vector Beams for Topological Enantio-Sensitive Imaging
A. Rodriguez, J. Edginton, A. Löhr +7
Molecular chiral discrimination is vital across chemistry and life sciences, yet optical approaches remain highly inefficient for small organic molecules. Here we turn vector beams…
Photonic architectures for synthetic chiral light-driven chiral sensing
Alexander Löhr, Justas Terentjevas, Patricia Vindel-Zandbergen +6
Molecular chirality gives rise to left- and right-handed enantiomers whose balance underpins biochemical function. Deviations from this enantiomeric excess are promising biomarkers…
Chiral Temporal Structures in Molecular Rotational Dynamics
A. G. Löhr, O. Smirnova, M. Mirahmadi
We introduce chiral rotational wavepackets: coherent superpositions of a few low-lying rotational states of a molecule for which the expectation value of a molecular axis traces a…
Using Large Language Models and Knowledge Graphs to Improve the Interpretability of Machine Learning Models in Manufacturing
Thomas Bayer, Alexander Lohr, Sarah Weiß +2
Explaining Machine Learning (ML) results in a transparent and user-friendly manner remains a challenging task of Explainable Artificial Intelligence (XAI). In this paper, we presen…
Chiral moments make chiral measures
Emilio Pisanty, Nicola Mayer, Andrés Ordóñez +2
We develop a family of chiral measures to quantify the chirality of a distribution and assign it a handedness. Our measures are built using the tensorial moments of the distributio…
Enantiosensitive exceptional points in open chiral systems
Nicola Mayer, Alexander Löhr, Nimrod Moiseyev +2
Exceptional points (EPs) are remarkable spectral degeneracies in a non-Hermitian system's parameter space, where both eigenvalues and eigenstates coalesce. Here, we show that in no…
