Light-matter Interaction

Excitons can simultaneously adopt atomic-like and solid-like characteristics when stimulated by light. The discovery opens up an important new avenue for the manipulation of excitonic as well as materials’ properties by light. more

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
