This manifestation will constitute the 7th edition of the Son et Lumière international school devoted to nanophononics, a multidisciplinary research field aiming at studying vibrations (phonons) in systems with a nanometric size or structuration, as well as their interaction with light and other waves. The two main goals of the school are to favor interactions between the different communities involved in nanophononics (optics, acoustics, thermal transfer, optomechanics, …) and to provide a detailed overview of this field for young researchers.
