Plausible "faster-than-light" displacements in a two-sheeted spacetime
Fabrice Petit, Michael Sarrazin
In this paper, we explore the implications of a two-point discretization of an extra-dimension in a five-dimensional quantum setup. We adopt a pragmatic attitude by considering the…
Matter localization and resonant deconfinement in a two-sheeted spacetime
Michael Sarrazin, Fabrice Petit
In recent papers, a model of a two-sheeted spacetime M4XZ2 was introduced and the quantum dynamics of massive fermions was studied in this framework. In the present study, we show…
Artificially induced positronium oscillations in a two-sheeted spacetime: consequences on the observed decay processes
Michael Sarrazin, Fabrice Petit
Following recent theoretical results, it is suggested that positronium (Ps) might undergo spontaneous oscillations between two 4D spacetime sheets whenever subjected to constant ir…
Quantum dynamics of massive particles in a non-commutative two-sheeted space-time
Fabrice Petit, Michael Sarrazin
We study a formal extension of the Dirac equation in the framework of a non-commutative two-sheeted space-time. It is shown that this approach naturally extends the classical Dirac…
Quantum dynamics of particles in a discrete two-branes world model: Can matter particles exchange occur between branes?
Michael Sarrazin, Fabrice Petit
In a recent paper, a model for describing the quantum dynamics of massive particles in a non-commutative two-sheeted spacetime was proposed. This model considers a universe made wi…
