Light-matter Interaction

Scientists pioneer an approach called self-referenced streaking, clocking Auger electrons with sub-femtosecond resolution. The breakthrough will unlock the broader potential for attosecond time resolution at X-ray free-electron lasers.

‘Kicking’ the atoms in a CuGeO₃ crystal with an infrared laser pulse can not only make the material transparent, but the transparency can also be controlled on an ultrafast femtosecond scale. more

The properties of molecules change significantly in the quantized electromagnetic fields of optical cavities. Researchers develop a new theoretical method to show that the ground- and excited-state chemistry of molecules can be modified by a confinement in space. more

Research team develops method to detect the dynamics of light on ultrasmall scales using a highly sensitive tracer molecule. The magnesium phthalocyanine molecule acts as a trigger switch which detects changes in the local electro-magnetic fields. more

Symmetrically coupled light and matter can produce a new combined state of light and electrons – a state which could be utilized in the design of new materials.  more
