  • David A. Harness, Quantum Continuum Gravitoelectromagnetic Mechanics.
    Static Maxwell-Einstein continuum mechanical gravitoelectromagnetic total stress energy momentum density tensor eigenvector matrix configuration space, provides flux for time dependent quantum mechanical eigenvalue matrix operator observables via Dirac-Noether conserved angular momentum probability current symmetry. Fundamental quantum continuum
    equation returns eigenvalues of photon gravitoelectromagnetic spectrum in units of Maxwell stress tensor pascals. Energization of off-diagonal stress tensor components results in electron-positron (moment of inertia x angular velocity) angular momentum origin of particle wave mass charge eigenvalues. In thought experiment test vs. general theory via pp-waves microlensing problem, where light-to-light gravitational attraction is four times matter-to-matter attraction, hypothesis predicts null result in area general theory known to break down on microscopic scale.

  • 94.6David Atkinson, Losing Energy in Classical, Relativistic and Quantum Mechanics.
    A Zenonian supertask involving an infinite number of colliding balls is considered, under the restriction that the total mass of all the balls is finite. Classical mechanics leads to the conclusion that momentum, but not necessarily energy, must be conserved. Relativistic mechanics, on the other hand, implies that energy and momentum conservation are always violated. Quantum mechanics, however, seems to rule out the Zeno configuration as an inconsistent system.

  • 92.8Bernd Binder, Self-Consistent Quantum-Gravitational Quadrupole Fluctuations.
    To establish a self-consistent system of mutually interacting gravitational quadrupoles, a characteristic number N of quantum masses µ are related to a characteristic velocity scaling. For this purpose a critical reference is defined by the flux and flux number of mass quanta constituting a confining unit field generating mass m_{G}=Nµ. In the field of m_{G} any small test mass orbits at unit distance r_{u} with unit velocity u (human artificial units). The velocity limit c with angular momentum quantum h is (...) assigned to the Schwarzschild black hole photon sphere with radius given by the Compton wavelength. For this quantum mass we find the constitutional scaling relation N \approx 3m_{G}/µ \propto (c/u)^5 which indicates a quadrupole exchange. The corresponding coupling strength can be exactly related to previous results confirming the quantum mass µ hidden in the action quantum related at the Planck scale to the gravitational coupling constant G by µ^4 G=1. The coupling deficits can be assigned to a duality of coupling and non-coupling fluxes with 4th power flux scaling. This fits very well to existing models assuming a non-gravitating vacuum energy to give a satisfactory answer to the cosmological constant problem. (shrink)

  • 90.1Sheldon Goldstein, Quantum Equilibrium and the Role of Operators as Observables in Quantum Theory.
    Bohmian mechanics is arguably the most naively obvious embedding imaginable of Schr¨ odinger’s equation into a completely coherent physical theory. It describes a world in which particles move in a highly non-Newtonian sort of way, one which may at first appear to have little to do with the spectrum of predictions of quantum mechanics. It turns out, however, that as a consequence of the defining dynamical equations of Bohmian mechanics, when a system has wave function ψ its configuration is typically (...) random, with probability density ρ given by |ψ|2, the quantum equilibrium distribution. It also turns out that the entire quantum formalism, operators as observables and all the rest, naturally emerges in Bohmian mechanics from the analysis of “measurements.” This analysis reveals the status of operators as observables in the description of quantum phenomena, and facilitates a clear view of the range of applicability of the usual quantum mechanical formulas.

  • 87.0Lee Smolin, Matrix Models as Non-Local Hidden Variables Theories.
    It is shown that the matrix models which give non-perturbative definitions of string and M theory may be interpreted as non-local hidden variables theories in which the quantum observables are the eigenvalues of the matrices while their entries are the non-local hidden variables. This is shown by studying the bosonic matrix model at finite temperature, with T taken to scale as 1/N, with N the rank of the matrices. For large N the eigenvalues of the matrices undergo Brownian motion due (...) to the interaction of the diagonal elements with the off diagonal elements, giving rise to a diffusion constant that remains finite as N goes to infinity. The resulting probability density and current for the eigenvalues are then found to evolve in agreement with the Schroedinger equation, to leading order in 1/N, with hbar proportional to the thermal diffusion constant for the eigenvalues. The quantum uctuations and uncertainties in the eigenvalues are then consequences of ordinary statistical uctuations in the values of the off-diagonal matrix elements. Furthermore, this formulation of the quantum theory is background independent, as the definition of the thermal ensemble makes no use of a particular classical solution. The derivation relies on Nelson's stochastic formulation of quantum theory, which is expressed in terms of a variational principle. (shrink)

  • 84.8Jim Bourassa & David Thomson (2006). A New Foundation for Physics. Infinite Energy Magazine (69):34.
    Modern physics describes the mechanics of the Universe. We have discovered a new foundation for physics, which explains the components of the Universe with precision and depth. We quantify the existence of Aether, subatomic particles, and the force laws. Some aspects of the theory derive from the Standard Model, but much is unique. A key discovery from this new foundation is a mathematically correct Unified Force Theory. Other fundamental discoveries follow, including the origin of the fine structure constant and subatomic (...) particle g-factors, a slight correction of neutron magnetic moment, a geometrical structure for charge, the quantification of electromagnetic charge as separate from electrostatic charge, a more precise meaning of spin, the quantification of space-resonance in five dimensions, and a new system of quantum units. The Aether quantifies as a fabric of quantum rotating magnetic fields with electromagnetic, electrostatic, and gravitational dipole structures. Subatomic particles quantify as angular momentum encapsulated in a quantum, rotating magnetic field. All quantum, atomic, and molecular processes can be precisely modeled, leading to discrete physics with new understandings and insights. (shrink)

  • 84.0Robert M. Richman (1999). The Use of One-Electron Quantum Numbers to Describe Polyelectronic Systems. Foundations of Chemistry 1 (2).
    Atomic states are rigorously characterized by the total orbital angular momentum and the total spin angular momentum, but chemists persist in the use of electron configurations based on one-electron quantum numbers and simplified rules for predicting ground state configurations. This practice is defended against two lines of criticism, and its use in teaching chemistry is encouraged with the claim that the inductive approach of Mendeleev and the deductive approach initiated by Schrödinger compose the consummate example of that interaction of empirical (...) and rational epistemologies that defines how chemists think.

  • 82.2Hans Halvorson (2001). On the Nature of Continuous Physical Quantities in Classical and Quantum Mechanics. Journal of Philosophical Logic 30 (1).
    Within the traditional Hilbert space formalism of quantum mechanics, it is not possible to describe a particle as possessing, simultaneously, a sharp position value and a sharp momentum value. Is it possible, though, to describe a particle as possessing just a sharp position value (or just a sharp momentum value)? Some, such as Teller, have thought that the answer to this question is No – that the status of individual continuous quantities is very different in quantum mechanics than in classical (...) mechanics. On the contrary, I shall show that the same subtle issues arise with respect to continuous quantities in classical and quantum mechanics; and that it is, after all, possible to describe a particle as possessing a sharp position value without altering the standard formalism of quantum mechanics.

  • 81.0Erik Curiel, On Tensorial Concomitants and the Non-Existence of a Gravitational Stress-Energy Tensor.
    Based on an analysis of what it may mean for one tensor to depend in the proper way on another, I prove that, under certain natural conditions, there can be no tensor whose interpretation could be that it represents gravitational stress-energy in general relativity. It follows that gravitational energy, such as it is in general relativity, is necessarily non-local. Along the way, I prove a result of some interest in own right about the structure of the associated jet bundles of (...) the bundle of Lorentz metrics over spacetime. (shrink)

  • 78.4Peter Kosso (2000). Quantum Mechanics and Realism. Foundations of Science 5 (1).
    Quantum mechanics is usually presented as a challenge to scientific realism, but I will argue that the details of quantum mechanics actually support realism. I will first present some basic quantum mechanical concepts and results, including the Einstein-Podolsky-Rosen (EPR) experiment and Bell's theorem, and do it in a way that everyone can understand. I will then use the physics to inform the philosophy, showing that quantum mechanics provides evidence to support epistemological realism.
