Based on the model of a ”soft” cellular space and deterministic quantum mechanics developed previously, the scattering of a free moving particle by structural units of the space – superparticles – is studied herein. The process of energy and inert mass transmission from the moving particle to superparticles and hence the creation of elementary excitations of the space – inertons – are analyzed ...

The binding energies of all hydrogen isotopes have been calculated successfully for the first time in a previous paper [J Fusion Energy, 30 (2011) 377], using only the electric and magnetic Coulomb’s laws, without using the hypothetical shell model of the nucleus and its mysterious strong force. In this paper, an elementary calculation gives the order of magnitude of the nuclear interaction. Th...

HEN A STRANGER, hearing that I am a physicist, asks me in what area of physics I work, I generally reply that I work on the theory of elementary particles. Giving this answer always makes me nervous. Suppose that the stranger should ask, “What is an elementary particle?” I would have to admit that no one really knows. Let me declare first of all that there is no difficulty in saying what is mea...

In standard Poincare and anti de Sitter SO(2,3) invariant theories, the existence of antiparticles is explained by using the fact that covariant equations have solutions with negative energies. In these theories a particle and its antiparticle are described by independent positive energy irreducible representations (IRs) of the symmetry group. Such an approach cannot be applied in de Sitter SO(...

frustration: elementary quasiparticles and many-particle bound states. Abstract The excitation spectrum of the two-chain S = 1/2 Heisenberg spin ladder with additional second neighbor frustrating interactions is studied by a variety of techniques. A description, based on a mapping of the model onto a Bose gas of hard-core triplets is used to determine the one-and two-particle excitation spectra...

In order to extend the Standard Model to TeV scale energies one must address two basic questions: (1) What is the complete description of the effective theory of fundamental particles at and below the electroweak scale? and (2) What is the dynamics responsible for electroweak symmetry breaking? The answers to these questions are crucial for addressing the third outstanding question of particle ...

After having briefly recalled the principles and methods on which the theory of scale relativity is founded, we apply our scale-covariant methods to the problem of recovering relativistic quantum mechanics. The withdrawal of the hypothesis of differentiability of space-time leads to the demonstration of the divergence of spacetime coordinates in terms of resolutions, then to the definition of s...

Introduction Inflation addresses most of the fundamental problems in cosmology – the origin of the flatness, large-scale smoothness, and small density inhomogeneities needed to seed all the structure seen in the Universe today. If correct, it would extend our understanding of the Universe to as early as 10−32 sec and open a window on physics at energies of order 10 GeV. However, at the moment t...

A recent experimental research carried out by Bohlein and collaborators shows how colloidal particle crystals trapped in laser interference fields can cast new light on elementary frictional processes in ideally controlled sliding systems. Driven colloidal friction provides an unprecedented realtime insight into the elementary microscopic dynamical mechanisms at play. In the present work we sim...

High-precision measurements of violations of fundamental symmetries in atoms are a very effective means of testing the standard model of elementary particles and searching for new physics beyond it. Such studies complement measurements at high energies. We review the recent progress in atomic parity nonconservation and atomic electric dipole moments (time reversal symmetry violation), with a pa...
