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 ...
