Dynamical Systems, Topology, and Conductivity in Normal Metals
Abstract
We present here a complete description of all asymptotic regimes of conductivity in the socalled "Geometric Strong Magnetic Field limit" in the 3D single crystal normal metals with topologically complicated Fermi surfaces. In particular, new observable integervalued characteristics of conductivity of topological origin were introduced by the present authors a few years ago; they are based on the notion of Topological Resonance which plays a basic role in the total picture. Our investigation is based on the study of dynamical systems on Fermi surfaces for the semiclassical motion of electrons in a magnetic field.
