The major research focus of the division is broadly on quantum matter, covering the full range from fundamental theory to application in material science and device design in quantum technology, with further smaller activity in biophysics and complex matter. The division has expertise in quantum many-body numerical techniques (Monte Carlo, exact diagonalization, DMRG, etc.) in addition to a strong history in mathematical physics including in integrable quantum systems. 

Ultimately the research aims at developing theoretical tools for understanding and finding new physical phenomena and materials, and thus contributing to future applications of such findings. The division is a frequent user of large-scale computer facilities and also runs a medium size local computer cluster network. The condensed matter theory division is active in research in, among others, the below topics.
