Correlated Electrons and the Lattice

The "Mott" (correlation-driven) metal-insulator transition is a topic of fundamental and continuing interest in condensed matter physics. It has long been known that metal-insulator transitions in most materials are accompanied by changes in crystal structure and atomic positions and may be affected by strain. In this talk, I outline recent progress towards a comprehensive understanding and show how the results assist in the understanding of recent experiments on strain and current controlled metal-insulator transitions and microstructure formation.
