Ignoring this fact often leads to erroneous interpretation of the experimental data. In quantum electrodynamics (QED), the instability of a physical vacuum is characterized by the formation of pairs of elementary particles. The article contains descriptions of experiments, that allow substantiate the quantum structure of vacuum and the reality of particles arising in a vacuum as a result of its polarization. The idea of "virtuality" of particles is connected with the inability of quantum field theory to describe the real mechanism of vacuum polarization. Keywords: vacuum; dark matter; polarization; electron; positron; proton; resonance INTRODUCTION particles and antiparticles in a vacuum under the action of external fields, relying on the In classical electrodynamics, vacuum is a corresponding the Klein-Gordon-Fock and "medium" with absolute dielectric and magnetic Diract equations. permeability (εₐ, μₐ), which are equal to the dielectric and magnetic constant (εₒ, μₒ).

  • The Five Common Particles
    The Five Common Particles The world around you consists of only three particles: protons, neutrons, and electrons. Protons and neutrons form the nuclei of atoms, and electrons glue everything together and create chemicals and materials. Along with the photon and the neutrino, these particles are essentially the only ones that exist in our solar system, because all the other subatomic particles have half-lives of typically 10-9 second or less, and vanish almost the instant they are created by nuclear reactions in the Sun, etc. Particles interact via the four fundamental forces of nature. Some basic properties of these forces are summarized below. (Other aspects of the fundamental forces are also discussed in the Summary of Particle Physics document on this web site.)

  • Dispersion Relations in Loop Calculations
    LMU–07/96 MPI/PhT/96–055 hep–ph/9607255 July 1996 Dispersion Relations in Loop Calculations∗ Bernd A. Kniehl† Institut f¨ur Theoretische Physik, Ludwig-Maximilians-Universit¨at, Theresienstraße 37, 80333 Munich, Germany Abstract These lecture notes give a pedagogical introduction to the use of dispersion re- lations in loop calculations. We first derive dispersion relations which allow us to recover the real part of a physical amplitude from the knowledge of its absorptive part along the branch cut. In perturbative calculations, the latter may be con- structed by means of Cutkosky’s rule, which is briefly discussed. For illustration, we apply this procedure at one loop to the photon vacuum-polarization function induced by leptons as well as to the γff¯ vertex form factor generated by the ex- change of a massive vector boson between the two fermion legs. We also show how the hadronic contribution to the photon vacuum polarization may be extracted + from the total cross section of hadron production in e e− annihilation measured as a function of energy. Finally, we outline the application of dispersive techniques at the two-loop level, considering as an example the bosonic decay width of a high-mass Higgs boson. arXiv:hep-ph/9607255v1 8 Jul 1996 1 Introduction Dispersion relations (DR’s) provide a powerful tool for calculating higher-order radiative corrections.

(U.S.S.R.) 48, 565-573 (February, 1965) The nonlinear additions to the Lagrangian of a constant electromagnetic field, caused by the vacuum polarization of a charged vector field, are calculated in the special case in which the gyromagnetic ratio of the vector boson is equal to 2. The result is exact for an arbri­ trarily strong electromagnetic field, but does not take into account radiative corrections, which can play an important part in the unrenormalized electrodynamics of a vector boson. The anomalous character of the charge renormalization is pointed out. 1.

  • A Discussion on Characteristics of the Quantum Vacuum
    A Discussion on Characteristics of the Quantum Vacuum Harold \Sonny" White∗ NASA/Johnson Space Center, 2101 NASA Pkwy M/C EP411, Houston, TX (Dated: September 17, 2015) This paper will begin by considering the quantum vacuum at the cosmological scale to show that the gravitational coupling constant may be viewed as an emergent phenomenon, or rather a long wavelength consequence of the quantum vacuum. This cosmological viewpoint will be reconsidered on a microscopic scale in the presence of concentrations of \ordinary" matter to determine the impact on the energy state of the quantum vacuum. The derived relationship will be used to predict a radius of the hydrogen atom which will be compared to the Bohr radius for validation. The ramifications of this equation will be explored in the context of the predicted electron mass, the electrostatic force, and the energy density of the electric field around the hydrogen nucleus. It will finally be shown that this perturbed energy state of the quan- tum vacuum can be successfully modeled as a virtual electron-positron plasma, or the Dirac vacuum.

BACKGROUND ON STANDARD MODEL OF COSMOLOGY Prior to developing the central theme of the paper, it will be useful to present the reader with an executive summary of the characteristics and mathematical relationships central to what is now commonly referred to as the standard model of Big Bang cosmology, the Friedmann-Lema^ıtre-Robertson-Walker metric. The Friedmann equations are analytic solutions of the Einstein field equations using the FLRW metric, and Equation(s) (1) show some commonly used forms that include the cosmological constant[1], Λ.

Box 94485, 1098 XH Amsterdam, The Netherlands; t.m.nieuwenhuizen@uva.nl; Tel.: +31-20-525-6332 2 International Institute of Physics, UFRG, Av. O. Gomes de Lima, 1722, 59078-400 Natal-RN, Brazil Academic Editors: Gregg Jaeger and Andrei Khrennikov Received: 19 February 2016; Accepted: 31 March 2016; Published: 13 April 2016 Abstract: De la Peña 1980 and Puthoff 1987 show that circular orbits in the hydrogen problem of Stochastic Electrodynamics connect to a stable situation, where the electron neither collapses onto the nucleus nor gets expelled from the atom. Although the Cole-Zou 2003 simulations support the stability, our recent numerics always lead to self-ionisation. Here the de la Peña-Puthoff argument is extended to elliptic orbits. For very eccentric orbits with energy close to zero and angular momentum below some not-small value, there is on the average a net gain in energy for each revolution, which explains the self-ionisation. Next, an 1/r2 potential is added, which could stem from a dipolar deformation of the nuclear charge by the electron at its moving position. This shape retains the analytical solvability. When it is enough repulsive, the ground state of this modified hydrogen problem is predicted to be stable. The same conclusions hold for positronium. Keywords: Stochastic Electrodynamics; hydrogen ground state; stability criterion PACS: 11.10; 05.20; 05.30; 03.65 1.

  • Lesson 1: the Single Electron Atom: Hydrogen
    Lesson 1: The Single Electron Atom: Hydrogen Irene K. Metz, Joseph W. Bennett, and Sara E. Mason (Dated: July 24, 2018) Learning Objectives: 1. Utilize quantum numbers and atomic radii information to create input files and run a single-electron calculation. 2. Learn how to read the log and report files to obtain atomic orbital information. 3. Plot the all-electron wavefunction to determine where the electron is likely to be posi- tioned relative to the nucleus. Before doing this exercise, be sure to read through the Ins and Outs of Operation document. So, what do we need to build an atom? Protons, neutrons, and electrons of course! But the mass of a proton is 1800 times greater than that of an electron. Therefore, based on de Broglie’s wave equation, the wavelength of an electron is larger when compared to that of a proton. In other words, the wave-like properties of an electron are important whereas we think of protons and neutrons as particle-like. The separation of the electron from the nucleus is called the Born-Oppenheimer approximation. So now we need the wave-like description of the Hydrogen electron. Hydrogen is the simplest atom on the periodic table and the most abundant element in the universe, and therefore the perfect starting point for atomic orbitals and energies. The compu- tational tool we are going to use is called OPIUM (silly name, right?). Before we get started, we should know what’s needed to create an input file, which OPIUM calls a parameter files. Each parameter file consist of a sequence of ”keyblocks”, containing sets of related parameters.

Lamb, Jr. [54] Man kann sich darüber streiten, ob die Welt aus Atomen aufgebaut ist, oder aus Geschichten. — R. D. Precht [165] ABSTRACT The quantum vacuum is subject to continuous spontaneous creation and annihi- lation of matter and radiation. Consequently, an atom placed in vacuum is being perturbed through the interaction with such fluctuations. This results in the Lamb shift of atomic levels and spontaneous transitions between atomic states — the properties of the atom are being shaped by the vacuum. Hence, if the latter is be- ing shaped itself, then this reflects in the atomic features and dynamics. A prime example is the Casimir-Polder effect where a macroscopic body, introduced to the vacuum in which the atom resides, causes a position dependence of the Lamb shift.

This is because superfluid electrons acquire an intrinsic moment of inertia me(2λL) , with λL the London penetration depth.

  • 1.1. Introduction the Phenomenon of Positron Annihilation Spectroscopy
    PRINCIPLES OF POSITRON ANNIHILATION Chapter-1 __________________________________________________________________________________________ 1.1. Introduction The phenomenon of positron annihilation spectroscopy (PAS) has been utilized as nuclear method to probe a variety of material properties as well as to research problems in solid state physics. The field of solid state investigation with positrons started in the early fifties, when it was recognized that information could be obtained about the properties of solids by studying the annihilation of a positron and an electron as given by Dumond et al. [1] and Bendetti and Roichings [2]. In particular, the discovery of the interaction of positrons with defects in crystal solids by Mckenize et al. [3] has given a strong impetus to a further elaboration of the PAS. Currently, PAS is amongst the best nuclear methods, and its most recent developments are documented in the proceedings of the latest positron annihilation conferences [4-8]. PAS is successfully applied for the investigation of electron characteristics and defect structures present in materials, magnetic structures of solids, plastic deformation at low and high temperature, and phase transformations in alloys, semiconductors, polymers, porous material, etc. Its applications extend from advanced problems of solid state physics and materials science to industrial use. It is also widely used in chemistry, biology, and medicine (e.g. locating tumors). As the process of measurement does not mostly influence the properties of the investigated sample, PAS is a non-destructive testing approach that allows the subsequent study of a sample by other methods. As experimental equipment for many applications, PAS is commercially produced and is relatively cheap, thus, increasingly more research laboratories are using PAS for basic research, diagnostics of machine parts working in hard conditions, and for characterization of high-tech materials.

  • 1 the LOCALIZED QUANTUM VACUUM FIELD D. Dragoman
    1 THE LOCALIZED QUANTUM VACUUM FIELD D. Dragoman – Univ. Bucharest, Physics Dept., P.O. Box MG-11, 077125 Bucharest, Romania, e-mail: danieladragoman@yahoo.com ABSTRACT A model for the localized quantum vacuum is proposed in which the zero-point energy of the quantum electromagnetic field originates in energy- and momentum-conserving transitions of material systems from their ground state to an unstable state with negative energy. These transitions are accompanied by emissions and re-absorptions of real photons, which generate a localized quantum vacuum in the neighborhood of material systems. The model could help resolve the cosmological paradox associated to the zero-point energy of electromagnetic fields, while reclaiming quantum effects associated with quantum vacuum such as the Casimir effect and the Lamb shift; it also offers a new insight into the Zitterbewegung of material particles. 2 INTRODUCTION The zero-point energy (ZPE) of the quantum electromagnetic field is at the same time an indispensable concept of quantum field theory and a controversial issue (see [1] for an excellent review of the subject). The need of the ZPE has been recognized from the beginning of quantum theory of radiation, since only the inclusion of this term assures no first-order temperature-independent correction to the average energy of an oscillator in thermal equilibrium with blackbody radiation in the classical limit of high temperatures. A more rigorous introduction of the ZPE stems from the treatment of the electromagnetic radiation as an ensemble of harmonic quantum oscillators. Then, the total energy of the quantum electromagnetic field is given by E = åk,s hwk (nks +1/ 2) , where nks is the number of quantum oscillators (photons) in the (k,s) mode that propagate with wavevector k and frequency wk =| k | c = kc , and are characterized by the polarization index s.

  • Dynamic Quantum Vacuum and Relativity
    Dynamic Quantum Vacuum and Relativity Davide Fiscaletti*, Amrit Sorli** *SpaceLife Institute, San Lorenzo in Campo (PU), Italy **Foundations of Physics Institute, Idrija, Slovenia sorli.amrit@gmail.com spacelife.institute@gmail.com Abstract A model of a three-dimensional quantum vacuum with variable energy density is proposed. In this model, time we measure with clocks is only a mathematical parameter of material changes, i.e. motion in quantum vacuum. Inertial mass and gravitational mass have origin in dynamics between a given particle or massive body and diminished energy density of quantum vacuum. Each elementary particle is a structure of quantum vacuum and diminishes quantum vacuum energy density. Symmetry “particle – diminished energy density of quantum vacuum” is the fundamental symmetry of the universe which gives origin to mass and gravity. Special relativity’s Sagnac effect in GPS system and important predictions of general relativity such as precessions of the planets, the Shapiro time delay of light signals in a gravitational field and the geodetic and frame-dragging effects recently tested by Gravity Probe B, have origin in the dynamics of the quantum vacuum which rotates with the earth. Gravitational constant GN and velocity of light c have small deviations of their value which are related to the variable energy density of quantum vacuum. Key words: energy density of quantum vacuum, Sagnac effect, relativity, dark energy, Mercury precession, symmetry, gravitational constant. PACS numbers: 04. ; 04.20-q ; 04.50.Kd ; 04.60.-m. 1.
