Viewing electrons on nanometer length scales and femtosecond timescales

The properties of materials can be controlled using light pulses with a time duration on the order of femtoseconds (0.000000000000001 s). Light can switch an insulating material into a conductive one and even create order out of disorder on the atomic scale. Here, we will visualise such phase transitions by probing them on nanometer length scales and femtosecond timescales with a new experiment.
