| Vanadium oxides count among classical examples for correlated materials presenting metal insulator transitions (MIT). Vanadium dioxide undergoes a MIT, accompanied by a structural transition, as a function of temperature, the origin of which - Mott or Peierls - has been much debated in the literature. Cr-doped Vanadium sesquioxide has been considered as a prototypical example of a Mott transition since the early days of correlated materials. We will present dynamical mean field results for the angle-resolved spectral functions of these compounds and discuss implications for the nature of the MITs. |
