On Quantum Entropy and Excess Entropy Production in a System-Environment Pure State
Phillip C. Lotshaw, Michael E. Kellman
We explore a recently introduced quantum thermodynamic entropy of a pure state of a composite system-environment computational "universe" with a simple system $\mathca…

Quantum Thermodynamics, Entropy of the Universe, Free Energy, and the Second Law
George L. Barnes, Phillip C. Lotshaw, Michael E. Kellman
We take the view that the standard von Neumann definition, in which the entropy of a pure state is zero, is in evident conflict with the statement of the second law that t…

Relativistic Symmetry and Entangled Correlations
Michael E. Kellman
It is argued that the standard quantum mechanical description of the Bell correlations between entangled subsystems is in conflict with relativistic space-time symmetry. Proposals…
