the Neugebauer Research Group
- Quantum Chemistry @ WWU -
We develop and apply smart quantum chemical methods for selective and efficient calculations on chemical processes in complex environments like solvents, proteins, molecular crystals, or surfaces. We work on subsystem-based Density-Functional Theory and density-based (QM/QM) embedding for ground and excited electronic states, and further develop these methods for molecular/spectroscopic properties.

- Perspective on wavefunction-in-DFT embedding methods
Subsystem TDDFT and Beyond:
- Read our JPCL Perspective Article on sTDDFT
- We have implemented an "exact" version of subsystem TDDFT by means of projection-based embedding.
- Find details on subsystem-based GW/Bethe-Salpeter Equation here.
Theoretical On-Surface Chemistry:
- In collaboration with the Studer and Fuchs groups at University of Münster, we have theoretically studied azo-bond formations on metal surfaces and the on-surface chemistry of aryl triflates.
- See our Nature Chemistry article on Si-Si bond formation on metal surfaces.
Methods for/Studies on Radicals and Radical Crystals:
- We use Density Embedding as a Quasi-Diabatization Tool for Spin-Density Calculations, and have applied this method for an Investigation of the Spin-Density Asymmetry in Photosynthetic Reaction Center Models after initial charge separation.
- We established a a black-box implementation of the so-called first-principles bottom up approach for predicting the cooperative, macroscopic magnetic behaviour of crystalline organic radicals.
- Find out here how to obtain magnetic exchange couplings from subsystem DFT.
