Materials Science
The research within materials science starts from the smallest of building blocks to see how they combine to produce the properties of materials.
Current projects:
Methods for magnetism and magnetization dynamics
We develop new theories and computational methods to study and understand fundamental magnetic phenomena. These methods are applied to predict new functional magnetic materials needed for future sustainable applications.
Long-term project, period 2010–present

Materials Theory
Skyrmions, particle-like winding magnetic structures, might be utilized in future computational applications. The image illustrates a skyrmion that has been stabilized by interfacial chemical disorder.
Chemistry of complex materials
Materials chemistry is of tremendous industrial importance (catalysis, batteries, pollution control, functional surfaces, ...) and at the same time these systems are hugely complex. This complexity is the overarching e-science challenge that we want to conquer. To achieve this goal we develop methods and models for multiscale simulation and characterisation, using a mix of physics-based and data-driven methods.

High-resolution computational modelling of domain formation in metal halide perovskite nanocomponents: Targeting next-generation solar energy technology
In the last few years, perovskites have been identified as an alternative material for solar cells, providing properties comparable to, or exceeding, those of the commonly used silicon. In addition, solar cells based on perovskite can be manufactured for a fraction of the cost and energy required when using silicon. A major focus has been put on Metal Halide Perovskites (MHPs), but to harness the high performance offered by MHPs in optoelectronic devices such as solar cells, and to ensure long-term device reliability, the current gaps in understanding of the relationships between nanoscale structure and properties in MHPs must be bridged. In order to do so, the project will take advantage of atom-scale phase field crystal (PFC) simulations to characterize the evolution of domains and defects in MHPs.

Data-inspired engineering of backstage atoms in quantum chemistry
The primary focus of this project is on developing and fine-tuning a toolbox for the approximate treatment of large systems, through a data-driven design of pseudo-atoms for the periphery of the most important part of a molecule or crystal.
