QUANTUM NATURE OF THE OF WAVE-PACKET ENTROPY INCREMENT
Authors:
S.A. Trigger.



Abstract:
The time-dependent Heisenberg uncertainty relation is considered for the case of "maximally classical" quantum states (MACS). For a system of noninteracting particles, MACS with a characteristic wave function width Ar irreversibly passes over into a state with a greater quantum uncertainty. In the course of this evolution, the joint entropy increases with a characteristic time scale r ~ ??^/h. On this basis one can assume that in the case of interacting parti?cles the entropy defined in the form of a corresponding functional of an exact wave function or (for a mixed state) of a density ma?trix will increase as distinct from the von Neumann entropy. The quantum nature of particles plays an important role in entropy heightening even for those system parameters for which the par?ticles are usually considered as absolutely classical. The manifes?tation of quantum properties (at least for free particles) increases with time. The impossibility to predict future can on this basis be regarded as a purely quantum property of matter not only for microscopic, but also for macroscopic physical objects.
