Title:

Chiral phononics: Controlling materials with a twist

Abstract:

Angular momentum of lattice vibrations is emerging as a fundamental quantity of interest that can be used to engineer functional properties of materials. In this talk, I provide an overview of current developments in the field and present recent predictions of novel physical phenomena arising from ultrafast chiral phonon excitation. I will further address the role of phonon chirality beyond angular momentum, showing that achiral crystals can be made chiral on demand..
