Ultrafast Dynamics in Condensed Matter

THz electromagnetic pulse

Welcome to the group of Ultrafast Dynamics in Condensed Matter!

Our research efforts focus on the use of strong laser fields (in particular in the near-infrared and terahertz range) to manipulate quantum materials out of equilibrium on the ultrafast time scales. The response of these materials is probed with femtosecond lasers or femtosecond x-ray pulses generated at free electron lasers. Particular focus is dedicated to the investigation of spin and phonon dynamics in condensed matter.

Principal Investigator: Stefano Bonetti


“Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pumping of ferrimagnetic alloys" is now published in Nature Communications!


“Terahertz-driven phonon upconversion in SrTiO3” is now published in Nature Physics! Read the summaries on the webpages of SU (popular) and Fysikum (for physicist wannabes)


The community proposal X-ray holography of ultrafast magnetism: femtosecond movies at the nanoscale led by our group has been allocated beam time during the first run at the SCS instrument at the European XFEL! Congratulations to everyone involved, Hamburg see you in May!
