Algebraic Constraint Quantization and the Pseudo-Rigid Body
Abstract
Description
The pseudo--rigid body represents an example of a constrained system with a nonunimodular gauge group. This system is treated along the guidelines of an algebraic constraint quantization scheme which focusses on observable quantities, translating the vanishing of the constraints into representation conditions on the algebra of observables. The constraint which is responsible for the nonunimodularity of the gauge group is shown not to contribute to the observable content of the constraints, i.e., not to impose any restrictions on the construction of the quantum theory of the system. The application of the algebraic constraint quantization scheme yields a unique quantization of the physical degrees of freedom, which are shown to form a realization of the so-called CM(N) model of collective motions.
