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.

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

Our work on understanding electron spin and structural dynamics in the bilayer irridates is out in Physical Review B now!
Daniel Perez sucessfully defended his thesis entitled "Inhomogeneity and Disorder in Ultrafast Phase Transitions" at ICFO.
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.
Naman Agarwal joins the group as a post doc after completing his PhD at the european XFEL and Hamburg University.
Nina moves from Barcelona to Aarhus to finish her PhD in Denmark. Welcome Nina!
