| Abstract: | Using concepts from quantum field theory, in particular local gauge invariance, effective actions, power counting and scaling limits, etc. I describe an approach towards classifying states of matter, in particular (ordinary and topological) insulators. Transport equations are derived. Applications to the quantum Hall effect, the spin Hall effect, 3D topological insulators and to the problem of the origin of cosmic magnetic fields are sketched. |
