Macroscopic magnetization in uniform magnetic fields

Abstract

The finding of a new formulation of the magnetization vector of a quantum system interacting with a static uniform magnetic field\cite{Selenu1} is reported. There a gauge invariant form of its divergence is shown being expressed as a function of the electronic current per state coupled with the Berry curvature of the quantum system. A Fourier analysis of the magnetization vector and magnetization density is reported as an application of the presented formula it could be applied in the context of computational modelling\cite{Martin} of quantum matter.
