    "abstract": "In this letter we show that the dichroism and ellipticity induced on a linear\npolarized light beam by the presence of a magnetic field in vacuum can be\nexplained in the framework of the de Broglie\u0027s fusion model of a photon. In\nthis model it is assumed that the usual photon is the spin 1 state of a\nparticle-antiparticle bound state of two spin 1/2 fermions. The other S=0 state\nis referred to as the \\emph{second} photon. On the other hand, since no charged\nparticle neither particles having an electric dipole are considered, no effect\nis predicted in the presence of electric fields and this model is not in\ncontradiction with star cooling data or solar axion search.",
