This international school will constitute the 7th edition of the Son et Lumière school series 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.

This edition was made possible by the help of various public and private sponsors listed in the "Sponsors" page and is organized by Aurélien Crut (Lyon 1 university), Pascal Ruello (Le Mans university), Yannick Guillet (Bordeaux university) and Matias Bargheer (Potsdam university). It will take place on the magnificient site of the physics school of Les Houches, located above the Chamonix valley.

Lectures will address six main themes:
1) Introduction to nanophononics, picosecond acoustics
2) Vibrational properties of nano-objects and nanostructures
3) Applications of phonons for industry,bioimaging and sensing
4) Emerging spectroscopies involving non-visible waves (X-rays, THz)
5) Nanoscale thermal transport
6) Optomechanics
