In recent years, machine-learning interatomic potentials (MLIPs) have become powerful tools for simulating molecular
liquids. Their reliability, however, depends on high-quality experimental data for systematic validation and benchmark-
ing. Scattering experiments provide detailed structural information: neutron and X-ray diffraction probe collective
correlations, radial distribution functions (RDFs) describe local atomic organization, and bulk densities provide a
complementary benchmark. Yet these data are scattered across publications and repositories and vary in units, nor-
malization, experimental conditions, and reported uncertainties. A reusable, well-documented collection is therefore
still missing.
The project will establish a curated, provenance-aware dataset of experimental scattering and density data for multiple liquid solvents, enabling consistent validation of accurate and transferable MLIPs.The student will:
• learn how scattering and molecular interactions reveal liquid structure and relate to RDFs and density;
• collect, standardize, and document experimental diffraction, RDF, and density data;
• create basic tools to check data quality, consistency, and provenance.
- Voraussetzungen
• experience with Python programming and numerical data analysis;
• basic knowledge of molecular simulation, statistical mechanics, or materials characterization;
• an interest in machine learning, MLIPs, molecular simulation, or scattering experiments;
• careful and systematic working habits.
