Landauniveaus, Eich- und Verschiebungsinvarianz

The system consisting of a charged point particle in a homogeneous magnetic field is translation invariant in the plane perpendicular to the field. Consequently, the Lagrangian and Hamiltonian are invariant up to a total time derivative. Yet, there is no gauge in which the quantized Hamiltonian manifests this symmetry. Translations are then tantamount to gauge transformations. We aim to pin where the the loss of manifest tranlation invariance occurs and to see whether it can be circumvented. As one line of the analysis we shall construct the path integral from the quantized theory, where we expect translation invariance to be manifest once again. Further, we will consider general models where the Hamiltonian requires some form of gauge fixing.
