Ultralocal Fields and their Relevance for Reparametrization Invariant Quantum Field Theory
John R. Klauder
Reparametrization invariant theories have a vanishing Hamiltonian and enforce their dynamics through a constraint. We specifically choose the Dirac procedure of quantization before…
On the Implementation of Constraints through Projection Operators
A. Kempf, J. R. Klauder
Quantum constraints of the type Q ψ= 0 can be straightforwardly implemented in cases where Q is a self-adjoint operator for which zero is an eigenvalue. In that case, the physical…
Coherent State Path Integrals without Resolutions of Unity
John R. Klauder
From the very beginning, coherent state path integrals have always relied on a coherent state resolution of unity for their construction. By choosing an inadmissible fiducial vecto…
Generalized Affine Coherent States: A Natural Framework for Quantization of Metric-like Variables
Glenn Watson, John R. Klauder
Affine variables, which have the virtue of preserving the positive-definite character of matrix-like objects, have been suggested as replacements for the canonical variables of sta…
