Non-local Coulomb interactions and metal-insulator transition in Ti${}_2$O${}_3$: a cluster LDA+DMFT approach

A. I. Poteryaev, A. I. Lichtenstein, G. Kotliar

We present an ab initio quantum theory of the metal-insulator transition in Ti${}_2$O${}_3$. The recently developed cluster LDA+DMFT scheme is applied to describe the many-body feature…
