Perturbations simplify the study of “super photons”

A study gives novel insight into properties which are often difficult to observe

11-Jun-2024 - Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This ...

Optimal information about the invisible

How do you measure objects that you can't see under normal circumstances?

27-Jan-2021 - Laser beams can be used to precisely measure an object’s position or velocity. Normally, however, a clear, unobstructed view of this object is required – and this prerequisite is not always satisfied. In biomedicine, for example, structures are examined, which are embedded in an irregular, ...

A new Approach to look inside of Molecules

28-Sep-2020 - In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer ...

Self-imaging of a molecule by its own electrons

Mapping the atomic motion during a molecular vibration

22-Sep-2020 - One of the long-standing goals of research on the light-induced dynamics of molecules is to observe time-dependent changes in the structure of molecules, which result from the absorption of light, as directly and unambiguously as possible. To this end, researchers have developed and applied a ...
