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.
