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!

Our new review article with Andrea Alú‘s and Pablo Alonso-Gonzalez‘s teams made the cover of the January 2024 of Nature Review Materials!

Yesterday, just in time before the holiday, Richarda submitted her PhD thesis. Woohoo!

Also, we have been quiet but productive with several new papers: First near-field imaging of shear polaritons in gallium oxide together with Josh‘s, Andrea‘s, and Lukas‘ [more...]

Giulia‘s and Sören‘s paper on Leaky Polaritons just got published, congratulations! This was a very nice collaborative work together with Peining Li and Andrea Alú, thanks so much!

Niclas Sven Müller joined the group as a new postdoc. He is an expert in strong coupling phenomena, and we are looking forward to working with him very much. Welcome!

Gonzalo Alvarez-Perez, a senior Ph.D. student with Pablo Alonso-Gonzalez at the University of Oviedo, Spain, just joined the group as for a 3-months visit. Love having you here!
