A tomography formalism for reconstructing the magnetodielectric properties from quantum interference — •Johannes Fiedler and Stefan Scheel — Uni Rostock, Institut für Physik, Rostock, Germany

Wave properties of particles are known from fundamental experiments, like the double-slit interference of electrons, done by Young and Fresnel. This effects can be described by the wave-particle duality with the de Broglie wavelength of a matter wave, λ = h/p. Similar experiments with neutral atoms and molecules [1,2] have shown an additional effect, that matter waves are accumulating phases depending on the grating distance. These phases are facilitated by the Casimir-Polder potential between scatterer and particles, which results from the fluctuations of the quantized electromagnetic field [3]. Here we will present a possible route towards reconstructing the electromagnetic response properties of grating material by scattering tomography.
