They found impossible silica structures

An international research group has discovered previously unknown phases of silica, with structures that should not be possible in nature. The theoretical foundation of the work has been calculated under the leadership of Igor Abrikosov.

Theoretical Physics

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.

Department of Physics, Chemistry and Biology (IFM)

Undergraduate teaching and research in the areas of biology, chemistry, materials and applied physics and theory and modelling are conducted at this department.
