To analyze and explain existing experimental observations, to make a systematics of the generated knowledge, and to use the knowledge for novel predictions.

Theoretical physics deals with understanding of nature. In our research we use fundamental principles and basic concepts to develop mathematical models that are then studied by means of analytical and numerical methods. The main goal for a theoretical study is to analyze and explain existing experimental observations, to make a systematics of the generated knowledge, and to use the knowledge for novel discoveries. 

Nowadays theoretical physics field is broad, dealing with scientific challenges from understanding of universe to elementary particles and quantum information.

Within our group, the focus lies on Condensed Matter Theory. We study materials, considering fundamental and applied questions, ranging from the behavior of matter at extreme compressions relevant e.g. for understanding of structure and properties of Earth’s core, to applications of theoretical tools in knowledge-based materials design.
