Artificial lipidic bilayers are widely used as a model for the lipid matrix in biological cell membranes. We use the Pockels electro-optical effect to investigate the properties of an artificial lipidic membrane doped with nonlinear molecules in the

Le temps a la reflexion, ou delai de Newton-Wigner, est un element-cle pour caracteriser l'interaction de la lumiere avec une interface. Nous montrons que l'on peut avoir acces experimentalement a ce temps pour plusieurs interfaces. Dans le cas de la

Publikováno v: Quantum and Semiclassical Optics: Journal of the European Optical Society Part B. 10:733-752

We describe an ongoing experiment to measure parity violation in atomic caesium, based on detection by stimulated emission. Our goal is to measure to 1 a left-right asymmetry of to test electroweak theory and look for new physics beyond the Standard
