| Abstract | |
We present simple analytical arguments explaining the universal emergence of electronic Griffiths phases as precursors of disorder-driven metal-insulator transitions in correlated electronic systems. A simple effective model is constructed and solved within dynamical mean field theory. It is shown to capture all the qualitative and even quantitative aspects of such Griffiths phases. (AU) | |
