Some Previous and Elementary Considerations on the Schrodinger Equation and on the Collapse of the Wave Function

Authors: Armando V.D.B. Assis
Comments: 15 Pages. Footnote [3] added.

This paper is intended to show the Schrodinger equation, within its structure, allows the manifestation of the wave function collapse within a very natural way of reasoning. In fact, as we will see, nothing new must be inserted to the classical quantum mechanics, viz., only the dialectics of the physical world must be interpreted under a correct manner. We know the nature of a physical system turns out to be quantical or classical, and, once under the validity of the Schrodinger equation to provide the evolution of this physical system, the dialectics, quantum or classical, mutually exclusive, must also be under context through the Schrodinger equation, issues within the main scope of this paper. We will show a classical measure, the obtention of a classical result, emerges from the structure of the Schrodinger equation, once one demands the possibility that, over a chronological domain, the system begins to provide a classical dialectic, showing the collapse may be understood from both: the structure of the Schrodinger equation as well as from the general solution to this equation. The general solution, even with a dialectical change of description, leads to the conservation of probability, obeying the Schrodinger equation. These issues will turn out to be a consequence of a general potential energy operator, obtained in this paper, including the possibility of the classical description of the physical system, including the possibility of interpretation of the collapse of the quantum mechanical state vector within the Schrodinger equation scope.

A Realist Interpretation of Quantum Mechanics that rules out Determinism

Authors: John R Ramsden
Comments: 10 Pages. First cut - comments welcome

We indicate how pursuit of a realist interpretation of Quantum Mechanics, starting from a simple and plausible physical principle and established Quantum Mechanics, leads to a physical picture almost as counter-intuitive but which among other things would if true confirm that the quest for a deterministic model of Quantum Mechanics is doomed to failure.

A New Look at the Position Operator in Quantum Theory

Authors: Felix M. Lev
Comments: 68 Pages. A version published in Physics of Particles and Nuclei has been considerably revised in view of our discussions with Anatoly Kamchatnov and his constructive criticism.

The postulate that coordinate and momentum representations are related to each other by the Fourier transform has been accepted from the beginning of quantum theory by analogy with classical electrodynamics. As a consequence, an inevitable effect in standard theory is the wave packet spreading (WPS) of the photon coordinate wave function in directions perpendicular to the photon momentum. This leads to several paradoxes. The most striking of them is that coordinate wave functions of photons emitted by stars have cosmic sizes and strong arguments indicate that this contradicts observational data. We argue that the above postulate is based neither on strong theoretical arguments nor on experimental data and propose a new consistent definition of the position operator. Then WPS in directions perpendicular to the particle momentum is absent and the paradoxes are resolved. Different components of the new position operator do not commute with each other and, as a consequence, there is no wave function in coordinate representation. Implications of the results for entanglement, quantum locality and the problem of time in quantum theory are discussed.

The Rise and Fall of Wave-Particle Duality

Authors: Alan M. Kadin
Comments: 12 Pages. Submitted to Foundational Questions Institute Essay Contest, June 25, 2012, http://fqxi.org/community/forum/topic/1296

A retrospective is presented of the rise and fall of Wave-Particle Duality as the central doctrine of quantum mechanics, from the viewpoint of the 2024 centennial of the matter wave. This is contrasted with the recent New Quantum Paradigm, in which there are no point particles or entangled probability waves, and classical trajectories follow directly from coherent quantum dynamics.

Quantum Quackery

Authors: William Dungan Jr.
Comments: 16 Pages. Bohr was wrong and Einstein was right, “God doesn’t play dice with the world.”

Peer review is no panacea; every generation must reevaluate empirical evidence in the context of its own time. For the past century, quantum mechanics has defied common sense. Consistent in every detail with holographic virtual images, Young’s double-slit experiment generates diffraction patterns with coherent light, even one photon at a time, while incoherent light does not. Hence, interference pattern analogies are flagrant misrepresentations of the facts. Bohr’s quantum leap scenario violates the second law of thermodynamics and contradicts phase transition temperatures. Common sense dictates that the stability of molecular bonds contradicts probabilistic, leaping electrons. Bell’s inequality, a specious proof of quantum mechanics, derives from a false premise whose revelation by Joy Christian went widely unnoticed. Misinterpreting the facts, the blind-leading-the-blind faith of quantum mechanics twisted inductive speculation into a Gordian knot of mass delusions. As long as peer review science chooses to legitimize theoretical speculation, the demarcation between science and pseudoscience will remain indefensible.

Binary Mechanics

Authors: James J Keene
Comments: 22 Pages.

Binary mechanics (BM) used a pair of relativistic Dirac equations of opposite handedness to guide quantization of space and time into binary bit loci in a cubic lattice restricted to zero or one states. The exact time development of this BM state vector is determined by the four bit operations -- unconditional, scalar, vector and strong -- applied sequentially, one each in a quantized time unit.

Quaternion Spin 2 Field Theory

Authors: Peter Hickman
Comments: 15 Pages.

In this paper solutions to the nature of Dark matter, Dark energy, Matter, Inflation and the Matter-Antimatter asymmetry are proposed The real spin representations of a 7d complex space are assumed to be the source of a chiral gauge group SU(8)xU(1) and a spin 2 quaternion field. The integral of the probability density of the spin 2 field results in a lower bound for r and consequently the Schwarzschild physical singularity is non-existent. Fermion mass is bounded by a lower and an upper limit. Cosmology of the universe is cyclic with no past or future singularities and the Cosmological density ratios are in agreement with WMAP 7 year data.
