Numerical Simulations Group
Research on the physical properties of ferroic materials like ferroelectrics or antiferromagnets or multiferroics combining electric and magnetic order is the core topic in our laboratory. The numerical simulations group contributes to this this research activities on several specific subjects, e.g. the study of critical behaviour at ferroic phase transitions or the often complex topology of domain structures. For this we deploy various numerical simulation techniques like Monte-Carlo or phase-field simulations.
Our research goes into the following directions:
- Modeling
- Visualization
- Prediction
