Quantum Backreaction on ``Classical'' Variables
Arlen Anderson
A mathematically consistent procedure for coupling quasiclassical and quantum variables through coupled Hamilton-Heisenberg equations of motion is derived from a variational princi…

Unitarity Restoration in the Presence of Closed Timelike Curves
Arlen Anderson
A proposal is made for a mathematically unambiguous treatment of evolution in the presence of closed timelike curves. In constrast to other proposals for handling the naively nonun…

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…
