6 Field-Theoretical Methods in Quantum Magnetism
... with g = 2/S the coupling constant, v = 2aJS the spin wave velocity and the topological angle θ = 2πS. If we want the action to be finite in an infinite system and at zero temperature, we have to impose that m tends to a fixed vector m0 at infinity in space and imaginary time. By making all the points a ...

Berry Curvature as a Multi-Band Effect in Boltzmann Equations
... tional metals, and that this richness originates form the spin structure of the system, one can conclude that it is intrinsically a two band effect. This means that we can not hope to achieve a realistic result from standard one band calculations, as reviewed by Rammer and Smith[10]. So, in order t ...
