Rotating frames and gauge invariance in two-dimensional many-body quantum systems

Abstract

We study the quantization of many-body systems in two dimensions in rotating coordinate frames using a gauge-invariant formulation of the dynamics. We consider reference frames defined by linear and quadratic gauge conditions. In both cases we discuss their Gribov ambiguities and commutator algebra. We construct the momentum operators, inner product and Hamiltonian in both types of gauges, for systems with and without translation invariance. The analogy with the quantization of QED in non-covariant gauges is emphasized. Our results are applied to quasi-rigid systems in the Eckart frame.
