Materials beyond the single electron approximation: From oxides to adatoms on silicon

Philipp Hansmann , MPI Chemical Physics of Solids, Dresden
Explaining experimental evidence and guiding the design of new materials for electronic functionality are the two main goals of electronic structure calculations. Due to their ground state sensitivity with respect to external perturbations and rich phase diagrams, correlated electron materials such as transition metal oxides or rare-earth heavy-fermion compounds are promising candidates for future electronic devices. It is for the same reasons, however, that a theoretical description becomes very challenging due to the need of non-perturbative approaches to the quantum many-body problem. The seminar will cover (with equal weight) an introduction to modern methods for the treatment of correlated electron materials as well as selected highlights of recent computations for correlated materials ranging from transition metal oxides to adatom lattices on the (111) surface of silicon.
