W66.00001: Toroidal magnetic clouds in the interplanetary space Cristian Bahrim, Evgeny Romashets, Talon Weaver In-situ magnetic and plasma measurements allow us to determine the size and orientation of clouds near the Earth’s orbit based on the formulae proposed by Romashets and Vandas (Geophysical Research Letters, 2003). Marubashi et al. (Solar Physics, 2015) applied this approach for finding the shape and speed of 53 toroidal clouds near the Earth's orbit. We utilize their findings to several events and analyze the motion and expansion of the clouds. We offer a more detailed look to the geomagnetic storm on May 15, 1997. In this case, the maximum speed of the cloud at 3 solar radii is close to 2500 km/s. The cloud’s arrival time (about 74 hrs) and speed near the Earth’s orbit (of 423 km/s) are in good agreement with observations (within +/- 7%). Temperature of solar wind is assumed constant or slowly variable on the trajectory of the cloud, while the major and minor radii are defined mostly by the interplanetary magnetic field magnitude, which depends on heliodistance as 1/r. The density of solar wind meets continuity requirement and velocity of solar wind is set such a way that it equals to the measurements at 1 AU, and is below 70 km/s close to the Sun. Density of the magnetic cloud is calculated from the condition of constant mass. It remains lesser than that of solar wind for most of travel time. The profiles of the density, magnetic field, and the size of the cloud versus heliodistance will be presented. Similarly, conditions in the solar wind outside of the cloud are available from modeling, as well. The quiet conditions in solar wind are determined in the period of one day prior to arrival of the cloud, given that the period provides almost constant values of density, velocity, and magnetic field. The average values inside the cloud are taken from measurements within the interval of Marubashi's list. |

W66.00002: Pico-photonics: Anomalous Atomistic Electrodynamic Dispersion in Silicon Sathwik Bharadwaj, Todd F Van Mechelen, Zubin Jacob The concept of photonic frequency and momentum dispersion has been extensively studied in artificial dielectric materials such as photonic crystals and metamaterials. However, atomistic dispersion of electrodynamic excitations in natural media is an unexplored frontier. Here, we propose the concept of atomistic electrodynamic dispersion as a solution to the Maxwell Hamiltonian of matter. The atomistic electrodynamic dispersion determines the functional frequency and momentum dependency of the transverse electrodynamic excitations. We introduce the microscopic transverse dielectric tensor derived from the electronic bandstructure to the Maxwell Hamiltonian. Using this theory, we show the existence of anomalous electromagnetic waves in the forbidden spectral region in silicon. The anomalous waves have sub-nano meter wavelengths in the pico-photonics regime. The recognition of anomalous waves in silicon is a direct consequence of including short-range local-field effects in the transverse dielectric response of the material. Moreover, at a given frequency, the anomalous waves are found to generate previously undisclosed electromagnetic energy contributions. Our findings demonstrate the evidence for existence of new electromagnetic phases of matter in natural media such as silicon. |

W66.00003: Pascal's Triangle Fractal Symmetries Nayan E Myerson-Jain, Shang Liu, Wenjie Ji, Cenke Xu, Sagar Vijay We introduce a model of interacting bosons exhibiting an infinite collection of fractal symmetries -- termed "Pascal's triangle symmetries" -- which provides a natural U(1) generalization of a spin-(1/2) system with Sierpinski triangle fractal symmetries. The Pascal's triangle symmetry gives rise to exact degeneracies, as well as a manifold of low-energy states which are absent in the Sierpinski triangle model. Breaking the U(1) symmetry of this model to Zp, with prime integer p, yields a lattice model with a unique fractal symmetry which is generated by an operator supported on a fractal subsystem with Hausdorff dimension dH = ln(p(p+1)/2)/ln p. The Hausdorff dimension of the fractal can be probed through correlation functions at finite temperature. The phase diagram of these models at zero temperature in the presence of quantum fluctuations, as well as the potential physical construction of the U(1) model are discussed. |

W66.00005: An Angular Velocity Operator for the Dirac Equation Basil S Davis The quantum mechanical description of rotation angle and angular velocity has received some attention in the non-relativistic domain. A non-relativistic rotation angle operator was proposed by Barnett and Pegg [Phys. Rev. A 41, 3427 (1990)]. The commutativity of rotation angle operators was investigated by Loss and Mullin [J. Phys. A: Math. Gen. 25 L235 (1992)], and an angular velocity operator was constructed by Abe [Phys Rev A 54/1, 93 (1996)]. All such treatments of angle and angular velocity operators have been non-relativistic. In this paper we derive a relativistic angular velocity operator for the Dirac Hamiltonian. This angular velocity operator is related to the position operator for the Dirac electron suggested by Barut and Malin [Rev. Mod. Phys. 40 (1968) 632], and Barut and Bracken [Phys. Rev. D 23 (1981) 2454]. The angular velocity operator so obtained is shown to yield the anomalous magnetic moment of the electron through an application of second order perturbation theory, where the free electron Dirac Hamiltonian is perturbed by a weak magnetic field. |

W66.00006: Harnessing symmetries in deriving general Electromagnetic-field transformations in special relativity RAJEEV K PATHAK, Salil K Bedkihal We demonstrate how manifest symmetry of the general oblique Lorentz-boost matrix in conjunction with the antisymmetry of the Electromagnetic (EM)-field tensor enable one to derive the classic EM-field transformations in special theory of relativity (STR) in a broader, rigorous, yet remarkably lucid perspective, under (i) General Lorentz-boosts; (ii) Arbitrary, instantaneous, proper 3-D rotations. Standard texts on electrodynamics ‘derive’ the EM-field transformations only by contemplating certain ideal, special static-charge and steady-current distributions with preferred symmetries, chosen geometries, invoking ‘longitudinal’ and ‘transverse’ components of the static fields so generated. Gratifyingly, our approach manifestly encompasses time varying fields and yields the transformation relations in a coordinate-free form. Further, the EM-field transformation under proper, instantaneous 3-D rotations is demonstrated to transform as a passive rotation of the coordinate axes. The present didactical exercise, amenable to be incorporated in graduate courses on relativistic electrodynamics, should serve as an excellent illustration on how cogent symmetry arguments simplify otherwise tedious calculations in STR, while endowing complete generality to the connections obtained. |

W66.00007: On the dynamics of a localized charge continuum with structural stability Sukalyan Bhattacharya This talk describes the general dynamics of a charged body assuming it to be a localized continuum instead of a point entity. Moreover, the system satisfies the criteria of perpetual stability instead of typical initial conditions in an electromagnetic problem. A continuum, even if extremely small, possesses many degrees of freedom including deformation and rotation exhibiting dynamics in multiple length- and time-scales. Such internal motion allows complex interplay between velocity and electromagnetic fields. This makes the body violate Newton's first law by inducing natural oscillations with synchronized translation and deformation. At the same time, though, Newton's second law is satisfied, as net momentum from matter and field is conserved combinedly. This realization from pure classical mechanics predicts quantum features like wave-particle duality leading to Planck's and de Broglie's laws as corollaries. Also, the deformation response of the localized continuum to an external force explains its bound states by yielding Schrodinger equation as the governing relation for its perturbative motion. Thus, the theory derived from classical mechanics seems to reproduce quantum phenomenology without any additional postulation. |

W66.00008: A point magnet near a ring magnet: Magnetostatic interaction energy. Niranjan Warnakulasooriya Mahaguruge, Dinuka H Gallaba, John J Marchetta, Duston Wetzel, Prachi Parashar, K. V Shajesh We show that the magnetostatic interaction energy between a point magnet and a ring magnet admits exact solutions in terms of complete elliptic integrals when the point magnet is off the axis of the ring magnet and has a simple solution in terms of rational functions when the point dipole is on the axis of symmetry of the ring magnet. The exact expression for the interaction energy exhibits an equilibrium point close to the axis of symmetry with a saddle point instability. The stability analysis requires us to find the force on the dipole, which is given in terms of the derivatives of the elliptic integrals in the energy. Our solution will be useful in investigations concerning magnetic levitation and Casimir levitation. |

W66.00009: A Refutation of Special Relativity Eric A Samuel The Special Theory of Relativity (SR) is shown to be untenable. SR is theoretically flawed because of its unjustified expectation of an inertial frame outcome for a non-inertial experimental design that places observer and apparatus in separate frames; a simple solution by Galilean velocity transformation indicates no time dilation. SR’s time dilation formulation is not invariant to rotations and velocity of the clock’s energy waves. Replacing the light clock by a sonar clock imposes the sound speed as an absurd universal speed limit. Key experiments thought to support SR, have also been remarkably reinterpreted using Newton’s Laws alone. The speed-limited E-field and spiral H-field trajectories of electrons are elegantly explained by augmenting the Lorentz force with a flux-proportional radiation damping Lentz force. Experiments upheld as favoring SR’s transverse Doppler effect, are exquisitely reinterpreted as due to impulsive momentum transfer to photons from accelerating emitters. Finally, Rossi’s classical experiments are re-analyzed to reveal μ-mesons traveling in the upper atmosphere at astonishing warp numbers up to 20. Consequently, the concept of time dilation, and its companion concept of Lorentz invariance are utterly indefensible and fundamentally unnecessary. |

W66.00010: 10 Great Reasons to Prove the Possibility of Speed Faster Than the Speed of Light Gh. Saleh, M.J. FARAJI Inexistence of the speed faster than light is a hypothesis made almost 100 years ago and so far, there has never been a definitive phenomenon provided to prove it. When Einstein expresses his theory of relativity, this was his important point that there was an ultimate cosmic speed limit, and that only massless particles could ever reach it. But scientists have always looking for particles that move faster than light, because prove of the existence of speed faster than light will cause a great changes in the future of physics. In this paper, we are going to explain 10 great and logical reasons for the possibility of speeds faster than of light. We have been used Hubble's law, Blueshift (Redshift), data from Hubble Space Telescope, etc. to prove that. The titles of these reasons are: Speed faster than light |

W66.00012: Unification of Quantum Mechanics and General Relativity by Principle of Central System Relativity and N-time Inflationary Model of Universe Surendra Mund I am presenting a new theory of cosmos named by me as N-time Inflationary Model of Universe which is satisfying and unifying both Quantum Mechanics and General Relativity or Microscopic and Macroscopic scale theories. In this theoretical perspective I have generalised uncertainty and correspondence principles and as well as General and Special Theory of Relativity. The two pillars of this theory are my two principles- "Principle of Central System Relativity" and "Principle of Universal Relativity" or the key points of this theoretical perspective are f-? transformation, variation in the speed of light, existence of two kind of bodies-Perfect and Imperfect, existence of N-bodies on n-different geometrical scales predicted by N-time inflationary model of universe, existence of N-type of Central Systems formed out by N-bodies etc. By Principle of central system relativity we can unify both microscopic and macroscopic scale theories by using the universal dynamics observed by observer at origin of Universe(from where all creation started). I also defined time as the evolution and flow of universal scalar fields. Also proved Wave Particle duality and Hizenburg's Uncertainty Principle as manifestation of phi-shi transformation and also in similar way postulates of special relativity like time dilation, length contraction , energy mass equivalence are also a limited part of phi-shai transformation. Einstein tried to unify Quantum Mechanics and General Relativity and came up with Unified Field Theory but he could not because he did not understood Principle of Central System Relativity. I proved in my first article that speed of light varies in different eras and epochs of universe and this proof is not declining Special Relativity completely. In this theoretical perspective I proved that there exists sub electrons and such other bodies which move around electrons also but we could not measured these yet. I also defined an alternative to mass energy equivalence as E=φψ which is more unique than Einstein's Mass energy equivalence. This variation in speed of light also consistent with Cherenkov Radiation effect and it also proves variation in the speed of Gravitational waves. I also defined my own field equations of gravity as a manifestation of variation in density of scalar field around a body and proved both General Relativity and This force is valid for atoms also or n-bodies exist in universe according to n-time inflationary model of universe. I also calculated age of universe in predicted by n-time inflationary model of universe. So, gravity is also valid in atoms but the proportionality constant is different in various central system for this force. I defined space time as a manifestation of Universal scalar field and there is a motion by universe of each and every bodies. This motion produces effect of Universal Relativity. I also defined the Newton's laws of motion in form of scalar field and these are only valid in perfect bodies like earth. I also proved that black holes are not starting of time but these cause new inflations in universe as minor singularities. |
