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…

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…
