Ultrafast Dynamics in Quantum Solids
Prof. Dr. Simon Wall
- Activities:
Ultrafast Dynamics of Quantum Solids (UDQS) investigates the properties of materials, such as high temperature superconductors, through their non-equilibrium electron, lattice and spin dynamics on femtosecond timescales (1x10-15s) and nanoscale length scales (1x10-9m). To do this we combine cutting edge optical experiments based at ICFO with X-ray techniques performed at scientific facilities around the world.
