In the presence of magnetic fields of strength about ~1 B0 = 2.35×105 T, the electronic structure of atoms and molecules changes drastically compared to the field-free case. Such magnetic fields are found on magnetic white dwarfs and are not reproducible on Earth. In the absence of experimental settings, the study of the chemical composition of the atmospheres of these stellar objects has to rely on theoretical predictions. 
Using our experience on finite-magnetic field quantum-chemical methods, multireference methods are developed in order to target open-shell atomic and molecular systems with significant static correlation. Specifically of interest are systems with a multiconfigurational character which is too complex or changes in different magnetic-field strengths and as a result cannot be accurately targeted by single-reference based approaches.
