Researchers from Göttingen (Germany) and Lausanne (Switzerland) have developed a new method to generate quantum light using an electron beam. more

Researchers from Göttingen and Marburg have succeeded in using light to specifically change the electronic state of a material. Their results show how ultrashort light pulses can switch nanoscale areas of a material between insulating and metallic states – precisely and without significant heat input. more

A research team from Göttingen and Barcelona (Spain) has used the quantum mechanical interference of electrons to visualize light field oscillations in a nanostructure. The experiment is based on an attosecond electron microscope developed by Claus Ropers’ group at the Max Planck Institute (MPI) for Multidisciplinary Sciences and the University of Göttingen, which reveals the interaction of matter and light in the nanocosmos. more

Transmission electron microscopes in combination with short light pulses make it possible to investigate non-linear optical processes. Researchers from Göttingen and Switzerland have now shown for the first time how electrons can distinguish complex light states in a microscopic light storage in an electron microscope. more

Researchers have succeeded in measuring interactions between electrons in the electron microscope. In the process, they discovered an “energetic fingerprint” in which the distribution of the velocities of the electrons is very characteristic of their respective numbers. With the help of their findings, they developed a new method that can increase the performance of various electron microscopes. more
