Ultrafast Dynamics of Quantum Materials


We are a new research group at Aarhus University that exploits ultra-short pulses of laser light from across the entire electromagnetic spectrum to explore and control the properties of materials. Our focus is on understanding the properties of "quantum materials", materials that show interesting and unexpected phenomena at unusually high temperatures, such as high temperature superconductivity. By using photons that range in energy from 5 meV to 15 keV we can study atomic, spin and electron dynamics on nanometer lengthscales and femtosecond timescales. Our work exploits laboratory sources of laser light, as well as the use of X-ray lasers around the world. 

Interested in joining? 

Are you interested in joining our group as a Postdoc or PhD student, or for a masters or bachelor's project? If so, contact us now to discuss the possibilities.

ERC StG for former group member

Congratulations to our former postdoc, Ernest Pastor, who has been awarded an ERC starting grant - PhotoDefect. 

Good luck with the new project!

New Publication

Our work on the use of optical pulses to program neural networks in phase change materials is now published in nanophotonics

The work was made in collaboration with Volker Sorger from George Washington University and Robert Simposon from the Singapore University of Technology and Design. 


New group member

Daniel Perez transfers from ICFO, Spain to join us as a post doc. 

Welcome Dani!


New pre-print

We have submitted our latest work on nanoscale imaging of the ultrafast phase transition in VO2 imaged using PAL-XFEL. Here we use spectroscopically resolved coherent diffractive imaging to observe local changes in the domain structure with <50 nm spatial resolution.

New Publication

Work from a theory collaboration with the group of Maciej Lewenstein at ICFO  has been published in Physical Review B


New Publication

Our work on understanding electron spin and structural dynamics in the bilayer irridates is out in Physical Review B now!


Daniel Perez Graduates

Daniel Perez sucessfully defended his thesis entitled "Inhomogeneity and Disorder in Ultrafast Phase Transitions" at ICFO. 

Congratulations Dani!


New pre-print

We have submitted a new pre-print on the photoinduced phase transition in V2O3. Here we show that the dynamics are governed by disorder and overdamping, rather than coherent motion, despite an ultrafast change in the potential symmetry.
