Mimicking potentials for acoustic-phonons by shaping their propagation through a nanoengineered structure
In a theoretical work, a team of researchers at C2N has proposed a novel nanoengineered approach to manipulate the way acoustic-phonons travel through a periodic structure. They have demonstrated that their phononic platform allows studying a variety of potentials …

Generation of light in a photon-number quantum superposition
Physicists at C2N have demonstrated for the first time the direct generation of light in a state that is simultaneously a single photon, two photons, and no photon at all. They showed that the same kind of light emitters …
