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!
Richarda leaves for Nashville
Sep 2024
After almost 5 years, Richarda left the group to start working as a PostDoc with Josh Caldwell. We will (already do) miss you dearly! Farewell!
Akash joins the group
Sep 2024
Akash Chandra Behera joins the group as a new Ph.D. student. He will work on implementing new two-color FEL experiments with the new project at the Max-Planck-Radboud-University center. Welcome!
Unai joins for a 4 month visit
Aug 2024
Unai Arregui, an expert simulations of nonlinear THz response in nanostructures, joins the group for a 4 month visit. Welcome, Unai!
Metasurface imaging
Jun 2024
Richarda and Niclas finally published their work on imaging SiC metasurfaces in Advanced Materials. This is also the first time we directly observed propagating polaritons in our SFG microscope. The work was featured on the FHI and the PC website. Congrats, Niclas and Richarda!
