Biography
P.-F. Cohadon’s current research activity is split in two distinct areas. On the one hand, optomechanics experiments at LKB on micro- or nanomechanical systems, which aim to demonstrate quantum properties of both light (under the effect of the motion of a movable mirror) and of a mechanical resonator (under the effect of radiation pressure of a laser beam). On the other, he works within theVirgo Collaboration on the expected radiation-pressure effects in the gravitational interferometer Advanced Virgo, as well as on the sensitivity gain achieved using squeezed light. Despite orders of magnitude between the characteristics of the different systems under study within the optomechanics field (the mass of the moving mirror for instance varies over 14 decades, from hundreds of pg to tens of kg), both activities are surprisingly related.
