Dynamics of Matter in a Unitary Relativistic Quantum Framework | Chapter 8 | Current Research Progress in Physical Science Vol. 7

The matter dynamics as a positively defined density P (xi,t)= M|y (xi,t )|2 was described and showed that, according to the general theory of relativity, such a distribution can be conceived only as a fragment of matter with a finite mass M equal to a mass  M0 , as a characteristic of the matter dynamics, M= M– the matter quantization. The group velocities of the Fourier conjugate representations in the coordinate and momentum spaces describe the dynamics of a quantum particle in agreement with the Hamiltonian equations, unlike the Schrodinger representation which is in disagreement with these equations. Under the action of an external (nongravitational) field, the acceleration of the quantum matter has two components: 1) A component perpendicular to the velocity, given by the relativistic mechanical component of the time-dependent phase, and 2) A component given by the additional field terms of this phase. A free quantum particle is described by a non-dispersing wave function  y(xi,t), contrary to the solution of the Schrödinger equation. A coherent electromagnetic field, in resonance with a system of active quantum particles in a Fabry-Perot cavity, has a wave vector approximately proportional to the metric elements, as the resonance frequency is approximately constant – a gravitational wave can be detected by the transmission characteristics of an active Fabry-Perot cavity. In a constant gravitational field, a quantum particle undertakes a velocity and an acceleration, which, at the boundary of a black hole are null – absorption and evaporation processes at the boundary of a black hole arise only by gravitational perturbations. Important perturbations, significantly deforming the gravitational spherical symmetry of a black hole, are produced by strong nuclear and electromagnetic forces leading to the big matter concentrations of the celestial bodies. Generally, a quantum particle is described by a time-space volume, called a graviton, with a spin of 2, and a distribution of a specific matter in this volume, with a half-integer spin for Fermions and an integer spin for Bosons. A graviton Lagrangian is obtained as a curvature integral on a graviton volume, and a Hamiltonian tensor is obtained for the gravitational coordinates and velocities.

Differential Equation of Particle Motion with Helical Structure | Chapter 1 | New Trends in Physical Science Research Vol. 6

 Electromagnetic radiations are waves, of course. The photoelectric effect led A. Einstein to suggest that light of frequency V is made up of distinct energy quanta with the formula epsilon = hv. We try to treat a thin beam of a conical wave train with energy hv as a photon and watch what occurs in order to follow Einstein's advice. We first demonstrate that such a train must be enclosed by a perfect reflection membrane with a lateral border of zero rest mass. Then we show that the membrane is divided into equal portions with the same quantity of various charges by a pair of symmetrical spirals with a maximum stress of infinity (Sigma max infty E2). If the field is sufficiently intensified and the mass and charge requirements are satisfied, the membrane will split into two "pm" charged particles with spins of h/2. The internal mass distribution and charge symmetry have been proved to be helical. Then, we demonstrate that the spin of this class of particles often consists of two components: translational motion and additional self-rotation caused by the translational motion of the spiral structure. Despite the fact that the wave function interpretation is different, we were able to show that the differential equation of motion particle's inner system is satisfied and resembles the Schrodinger equation.

The Central Role of Spin in Celestial Body Motion Mechanics: With Assistance from Gravity, Centrifugal Force and Weightlessness | Chapter 3 | New Trends in Physical Science Research Vol. 5

 The key findings we present in this chapter are that the axial rotation speeds of the solar system planets are linearly related to their masses, that the orbital and axial rotation speeds of the synchronously rotating large, close-in satellites of the gas and ice giants are positively related to the size of their respective mother bodies, and that the larger the stars and even galaxies are, the faster they rotate on their axes and also move radially in space. All of these discoveries show that celestial bodies' axial spin is an intrinsic, autonomous feature, similar to the well-known basic properties of matter, such as the strong and weak nuclear forces, gravity, and electromagnetic. We further claim that this axial rotation of bodies is the foundation of their motion mechanics and how such movements might continue indefinitely. When we analyse how all movements are coordinated to bring order to the cosmos, we can see how all satellite bodies orbit their mother bodies in the same counterclockwise direction as the mother bodies' axial rotation. We realise that for this fundamental attribute of matter to work, it is necessary to coordinate such movements with reciprocal gravity, centrifugal force, and the bodies' weightlessness. As a result, many of the postulates of current cosmology, including as black holes, dark matter, dark haloes, negative energy, and so on, are no longer necessary. When galaxies travel circumferentially through space, Such motions will produce the illusion of the cosmos spinning on its axis, as stated in this chapter.

Space-time Gets Reversed Only for Fermions where as Space-time is Identical for Bosons: Scientific Explanation | Chapter 11 | Current Approaches in Science and Technology Research Vol. 10

 There are essentially two types of particles in particle physics. Bosons and fermions are the two types of particles. In both of them, particles are separated into subcategories. A fermion is a particle with an odd half-integer spin, such as 1/2, 3/2, or others. Fermions include quarks, leptons, protons, and neutrons. Integer spin particles, such as 0, 1, 2, and so on, are known as bosons. Photons, Gluons, W+, W-, Z0 bosons, Higgs bosons, Mesons, and other bosons are examples. Fermions are matter particles (with mass) that have a considerable quantity of energy. Bosons are force-carrying particles. In this chapter, I'll show how only fermions interact with space-time and how their interactions are reversed. Bosons interact in space-time but are not reversible. Space-time is reversed in anti-particles (fermions), whereas space-time is identical in bosons. As a result, all matter particles have anti-particle counterparts, but none of the force-carrying particles have anti-particle counterparts.

Critical Research: Effect of Cherenkov Radiation on Superluminal Free Spin-half Particles Motion in Spacetime | Chapter 12 | New Insights into Physical Science Vol. 5

 

Conservation laws, consisting of the existence of quantities which do not change in time, independent
of the dynamical evolution of a system, are crucial and vital for the construction of any dynamical
system theory. The basic properties such as conservation of energy, momentum, angular momentum,
charge, isospin, or generalization thereof are fundamental and must be guaranteed by a physical
system, if it is to give a valid description of nature. One persistent objection against the concept
of superluminal entities is based on the anticipation of fast energy loss which could be incurred
under Vavilov-Cherenkov radiation, with the consequent prediction that no such particles could be
detected. Yet presently, no theoretical or experimental explication exists which justifies this claim.
Here we show, in the limit of a kinematically permissible and non-dispersive medium, that energy
conservation is feasible. Corresponding to radiation intensities from large energy-momentum transfer,
when the parameter
k of the generalized linear velocity of the superluminal free spin-half field is made
sufficiently large, Cherenkov cone becomes flattened at
90o with direction of motion, bringing the
radiated energy to merge with the circulating energy flow in the wave field of the particle.
