In classical mechanics, a phonon designates a normal mode of vibration. A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency. Every physical property of a solid-state system that is determined by the position of the atoms is strongly affected by acoustic phonons.

In our team we focus on nanophononics: we generate, manipulate, and detect acoustic phonons at the nanoscale, and control how they interact with other excitations. Unlike audible sound, there are no readily available sources and detectors of acoustic phonons, therefore our experiments rely on optical techniques.

If you want to know more about how we control these atomic vibrations, and how light can be used to study them, navigate through our site! We are just starting to update it, so come back soon for more news!
