New name

We have a new name! Ultrafast dynamics of quantum solids (UDQS). We decided to change the name of the group to better reflect the direction our group is taking. More details on how we combine ultrafast optical and X-ray techniques to study the properties of quantum solids will appear soon!

Science

UODS uses light to understand and manipulate the properties of solids by exploiting their non-equilibrium response to femtosecond pulses of laser light. We aim to understand how electrons, phonons and spins interact to determine the properties of materials, such as magnetism, insulator-metal transitions and superconductivity. We investigate how light can be used to effectively and efficiently manipulate these interactions in order to control material properties. This is achieved by exploiting the ultrafast timescale in order to access that are not possible in thermal equilibrium.

In order to probe these processes our group combines advanced laser-lab based time-resolved optical spectroscopies with cutting edge experiments that can only be performed at world-leading, large-scale research facilities. This enables us to exploit the full power of the electromagnetic spectrum and utilize wavelengths from hundreds of microns down to sub-nanometers.
