Superluminality and Finite Potential Light-Barrier Crossing

Superluminal movements are subject of discussion since many decades. The present work investigates how an electrical charged real matter particle can traverse the energy barrier at the speed of light

Tunnelling of Hermite-Gaussian wavepackets

We examine the tunnelling process of incident Hermite-Gaussian wavepackets which feature several nodes and peaks. An analytic formula for the transmitted wave function is developed which applies to

From the Photon to Maxwell Equation. Ponderations on the Concept of Photon Localizability and Photon Trajectory in a de Broglie-Bohm Interpretation of Quantum Mechanics

In this paper using the Clifford bundle formalism we show how starting from the photon concept and its relativistic Hamilton-Jacobi equation (HJE) we immediately get (with a simple hypothesis

Revising Whitehead’s Notion of Society in the Light of Contemporary Physics

Abstract This article argues that Joseph A. Bracken’s revisions of Alfred North Whitehead’s derivative notion of “society” are plausible in view of developments in physics since Whitehead. In

Zero time tunneling: macroscopic experiments with virtual particles

Feynman introduced virtual particles in his diagrams as intermediate states of an interaction process. They represent necessary intermediate states between observable real states. Such virtual

Relativistic tunnelling time for electronic wave packets

We have analyzed the influence of the wave packet size in the relativistic tunnelling time τ and its uncertainty Δτ when it traverses a given potential barrier. The analytical expressions obtained

Some Issues in Relativistic Spacetime Theories

The chapter has as main objective to clarify some important concepts appearing in relativistic spacetime theories and which are necessary of a clear understanding of our view concerning the

Dispersion relations and causality: does relativistic causality require that n(ω) → 1 as ω → ∞ ?

In this paper it is shown that if the refractive index, or rather, [ n(ω) -1 ] satisfies the dispersion relations then, it is implied by Titchmarsh's theorem that, n(ω) → 1 as ω→ ∞. Any other

Dynamic pattern of finite-pulsed beams inside one-dimensional photonic band gap materials

The dynamics of two-dimensional electromagnetic (EM) pulses through one-dimensional photonic crystals (1DPC) has been theoretically studied. Employing the time expectation integral over the Poynting
