Does the Non-Locality of Quantum Phenomena Guarantee the Emergence of Entropy?

Quantum-Mechanical objects and phenomena have a different nature, and follow a different set of rules, from their classical counterparts. Two interesting aspects are the superposition of states and the non-locality of objects and phenomena. A third aspect, that gives quantum-mechanical objects which have common roots a non-local connection, is quantum entanglement. This paper takes up the question of whether these three properties of quantum mechanical systems facilitate the action of entropy's increase, in terms of creating a condition where energy is dispersing, or going from being localized to being more spread out over time. Quantum Mechanics gives each quantum entity the nature of a container or vehicle for both energy and information, some part of which is necessarily non-local. The author feels that quantum-mechanical systems take on aspects of computing engines, in this context. He discusses how the onset of chaos is possible with even the simplest calculational processes, how these processes also result in complexity building, and why both of these dynamics contribute to the character of entropy as observed in ordinary affairs, or with macroscopic systems.

How the Classical World Got Its Localization: an Elementary Account of How the Age of the Universe May be Implicated in the Quantum-Classical Transition

Authors: C. L. Herzenberg
Comments: 11 Pages.

An expanding universe of finite duration appears to impose limits on the temporal and spatial extent of quantum waves. These limitations seem to be able to bring about localization for sufficiently large quantum objects that can resemble classical behavior. A threshold for a transition from quantum to classical behavior of a physical object is derived in terms of the magnitude of its moment of inertia.

On Representing Particle By a Standing Luminal Wave-Revisiting de Broglie's Phase Wave

Authors: V.A.Induchoodan Menon
Comments: 12 Pages.

De Broglie when he introduced the concept of the phase wave to represent a particle, he assumed that in the rest frame of reference the particle will have the form of a standing vibration. According to the author, this was a serious mistake. He shows that instead, had de Broglie assumed a standing luminal wave structure for the particle, it would have led him to very exciting insights. The author shows that in a relativistic transformation the average energy and the momentum of the forward and the reverse waves forming the standing wave transform exactly like the energy and momentum of a particle. Besides, the plane wave expansion which is used to represent a particle in quantum mechanics is found to emerge directly from this standing wave structure. He proposes to extend the approach to incorporate the spin of the particle and also provide a simple explanation for the Pauli's exclusion principle.

On Nonlinear Quantum Mechanics, Brownian Motion, Weyl Geometry and Fisher Information

Authors: Carlos Castro, Jorge Mahecha
Comments: 16 pages, This article appeared in Progress in Physics vol. 1 (2006) 38-45.

A new nonlinear Schrödinger equation is obtained explicitly from the (fractal) Brownian motion of a massive particle with a complex-valued diffusion constant. Real-valued energy plane-wave solutions and solitons exist in the free particle case. One remarkable feature of this nonlinear Schrödinger equation based on a ( fractal) Brownian motion model, over all the other nonlinear QM models, is that the quantum-mechanical energy functional coincides precisely with the field theory one. We finalize by showing why a complex momentum is essential to fully understand the physical implications of Weyl's geometry in QM, along with the interplay between Bohm's Quantum potential and Fisher Information which has been overlooked by several authors in the past.
