Holography with electrons
The Hungarian Dennis Gábor discovered the principle of holography in theoretical work in 1947, when he tried to improve the resolution of electron microscopes. However, holography first became…
The puzzle of slow electrons
In 2009, the journal Nature Physics called it the "Ionization Surprise". So far, physicists believed that they would understand the ionization of atoms by strong laser fields well. But when they…
Even more power for laser power packages
Either with tremendous force or very quickly in a row - that's how you could describe the current state of laser technology. Physicists at the Max Born Institute (MBI) in Berlin want to combine both…
Elementary particles in couple dance
Researchers at the Max-Born-Institut in Berlin directly measure the position of electrons and protons during a chemical reaction with ultrashort X-ray flashes.

How electrons move
To understand an atom or a molecule, physicists must not only know their internal structure, but also be able to describe the motion of the electrons. Due to the extremely high speed, this was not…
A look inside of molecules
To not only observe but really understand a chemical reaction, scientists need to know the behavior of electrons within molecules. Until now, it has not been technically possible to observe electrons…
Record set up for shortest controllable time
Optical methods allow real-time investigations on the shortest time scales, which are not accessible by other methods. With lasers, light pulses of 100 attoseconds can be generated today (1…
