It is shown that a two-brane world made of two domain walls can be seen as a
noncommutative two-sheeted spacetime under certain assumptions. This
equivalence implies a model-independent phenomenology: Matter swapping between
the two 3-branes (or sheets) is predicted through fermionic oscillations
induced by magnetic vector potentials. This phenomenon, which might be
experimentally studied, could reveal the existence of extra dimensions in a new
and very affordable way.
