The Lambrecht lab develops and applys electronic structure approaches to help guide discoveries in catalysis, spectroscopy, and materials chemistry. They develop electronic structure and embedding methods that yield an accurate and computationally feasible description of chemical reactions in solvent or solid environments. In cooperation with experiment, they aim at gaining insights into the thermodynamics, kinetics and spectral signatures along catalytic pathways. Another focus is to provide rationales for the improvement of catalysts. They are working on decomposition methods that allow us to extract correlations between electronic structure descriptors for ligands and solvents and thus ultimately allow to make recommendations for more active catalyst systems. Their research areas include:
- Developing reduced-scaling first principles approaches for expedited predictions of molecular and materials properties: The aim is to enable calculations on larger systems than conventionally possible, which allows for more realistic chemical models. The scaling reduction is achieved by screening approaches exploiting the fact that some interactions between electrons (such as dispersion or vdW forces) are short-ranged and can therefore be neglected if the distance is big enough. Other approaches developed in the lab involve sparse matrix techniques, multi-scale approaches, as well as tensor decompositions.
- Energy decomposition approaches to split infrared and other spectral signatures into chemically meaningful contributions and to facilitate force field development.
- Simulating paramagnetic resonance spectra to identify the structures of metal binding sites in biological systems.
- Metal nanoparticles (optical excitation and catalysis).
