Different routes to the Mott insulator

Today I am giving a seminar Destruction of quasi-particles near the Mott transition (slides) at the Physics Department of the Indian Institute of Science in Bangalore.
The talk is largely based on a PRL which shows how Dynamical Mean-Field Theory (DMFT) can give a quantitative description of the optical conductivity of a family of organic charge transfer salts close to the Mott transition.
For a much broader context see this review. The talk briefly stresses that the nature of the quasi-particles in the metallic phase near the Mott transition for the band-width controlled and the filling-controlled Mott transitions are distinctly different.
