Welcome to the Lattice Dynamics group website!

Our group is interested in optical phonons in polar dielectric crystals and their heterostructures. We use various linear and nonlinear mid-infrared to THz spectroscopy techniques, employing the Infrared Free Electron Laser (IR-FEL) at the FHI as an intense and tunable light source.

Using this unique laser, we study various problems ranging from infrared nanophotonics to phase transitions in complex oxides. Check out our research page and our recent publications for more information!

New group member: Giulia
Apr 2021
Giulia has joined the team as a new Ph.D. student. She will work on far-infrared non-linear nanophotonics. Welcome, Giulia!
