  • Title: First-principles calculation of atomic forces and structural distortions in strongly correlated materials.
    Author: Leonov I, Anisimov VI, Vollhardt D.
    Journal: Phys Rev Lett; 2014 Apr 11; 112(14):146401. PubMed ID: 24765993.
    Abstract:
    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 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, SrVO3, and KCuF3.
