Effective Band Structure of Correlated Materials - The Case of VO2
Jan M. Tomczak, Silke Biermann
Vanadium dioxide, VO2, and its metal-insulator transition at T=340K continues to receive considerable interest. The question whether the physics of the insulating low-temperature p…
Multi-orbital Effects in Optical Properties of Vanadium Sesquioxide
Jan M. Tomczak, Silke Biermann
Vanadium sesquioxide, V2O3, boasts a rich phase diagram whose description necessitates the accounting for many-body Coulomb correlations. Spectral properties of this compound have…
Materials Design using Correlated Oxides: Optical Properties of Vanadium Dioxide
Jan M. Tomczak, Silke Biermann
Materials with strong electronic Coulomb interactions play an increasing role in modern materials applications. "Thermochromic" systems, which exhibit thermally induced changes in…
Bandwidth and Fermi surface of Iron-Oxypnictides: covalency and sensitivity to structural changes
Veronica Vildosola, Leonid Pourovskii, Ryotaro Arita +2
Some important aspects of the electronic structure of the iron oxypnictides depend very sensitively on small changes in interatomic distances and bond angles within the iron-pnicto…
