  We introduce a novel computational approach for the investigation of complex
correlated electron materials which makes it possible to evaluate interatomic
forces and thereby determine atomic displacements and structural
transformations induced by electronic correlations. It combines \textit{ab
initio} band structure and dynamical mean-field theory and is implemented with
the linear-response formalism regarding atomic displacements. We apply this new
technique to explore structural transitions of prototypical correlated systems
such as elemental hydrogen, SrVO$_3$, and KCuF$_3$.
