Quantum mechanical composition laws in reparameterization invariant systems
J. J. Halliwell, M. E. Ortiz
This paper gives a brief description of the derivation of a composition law for the propagator of a relativistic particle, in a sum over histories quantization. The extension of th…

Quantum-Mechanical Histories and the Uncertainty Principle. II. Fluctuations About Classical Predictability
J. J. Halliwell
This paper is concerned with two questions in the decoherent histories approach to quantum mechanics: the emergence of approximate classical predictability, and the fluctuations ab…

An Information-Theoretic Measure of Uncertainty due to Quantum and Thermal Fluctuations
Arlen Anderson, Jonathan J. Halliwell
We study an information-theoretic measure of uncertainty for quantum systems. It is the Shannon information of the phase space probability distribution $\la z | ρ| z \ra $, whe…
