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 on 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.

Two back-to-back articles published in the Physical Review Letters, Ultrafast Amplification and Nonlinear Magnetoelastic Coupling of Coherent Magnon Modes in an Antiferromagnet and Optical Frequency Up-Conversion of the Ferromagnetic Resonance in an Ultrathin Garnet Mediated by Magnetoelastic Coupling We revealed the key role of the lattice, via magnetoelasticity, in the ultrafast spin dynamics of an antiferromagnet and of a ferrimagnet.


“Nanoscale Transient Magnetization Gratings Created and Probed by Femtosecond Extreme Ultraviolet Pulses” is now published in Nano Letters! Congratulations to Vivek, Matteo and all co-authors! We transiently "patterned" a magnetic layer at the 10 nm scale with light! Read the news at Elettra


“Inertial spin dynamics in ferromagnets” is now published in Nature Physics! Congratulations to Neeraj, Nanna, Debanjan and all co-authors! Read the news at UniVe and short summary at Fysikum
