Thermopower of the Correlated Narrow Gap Semiconductor FeSi and Comparison to RuSi
Jan M. Tomczak, K. Haule, G. Kotliar
Iron based narrow gap semiconductors such as FeSi, FeSb2, or FeGa3 have received a lot of attention because they exhibit a large thermopower, as well as striking similarities to he…
Combined GW and dynamical mean field theory: Dynamical screening effects in transition metal oxides
Jan M. Tomczak, Michele Casula, Takashi Miyake +2
We present the first dynamical implementation of the combined GW and dynamical mean field scheme ("GW+DMFT") for first principles calculations of the electronic properties of corre…
Many-body effects in iron pnictides and chalcogenides -- non-local vs dynamic origin of effective masses
Jan M. Tomczak, M. van Schilfgaarde, G. Kotliar
We apply the quasi-particle self-consistent GW (QSGW) approximation to some of the iron pnictide and chalcogenide superconductors. We compute Fermi surfaces and density of states,…
