Query: Metal-Insulator Transition and Lattice Instability of Paramagnetic V2O3   We determine the electronic structure and phase stability of paramagnetic
V$_2$O$_3$ at the Mott-Hubbard metal-insulator phase transition, by employing a
combination of an ab initio method for calculating band structures with
dynamical mean-field theory. The structural transformation associated with the
metal-insulator transition is found to occur upon a slight expansion of the
lattice volume by $\sim 1.5$ %, in agreement with experiment. Our results show
that the structural change precedes the metal-insulator transition, implying a
complex interplay between electronic and lattice degrees of freedom at the
transition. Electronic correlations and full charge self-consistency are found
to be crucial for a correct description of the properties of V$_2$O$_3$.
