Protecting light beams from gain and loss – International research team demonstrates robust light propagation in open systems for the first time

A German research team has successfully demonstrated robust light propagation in open systems using parity-time (PT) symmetry. By dynamically distributing gain and loss over time, the researchers were able to create a protected edge channel that retains its average amplitude and enjoys full robustness.

Stop-motion photons: Localized light particles on the road

Scientists at the University of Rostock have made a groundbreaking discovery in the field of quantum mechanics. Localized light particles have been observed on long optical fibers, transcending the mechanism previously considered by Phil Anderson's theory of Anderson localization. This new class of disorder allows for the abrupt transp...

Laser takes pictures of electrons in crystals

Researchers have developed a new laser-based microscope that can resolve the distribution of electrons in crystal lattices with unprecedented resolution. The technique, known as Light Picoscopy, uses powerful laser pulses to drive electrons into fast motion, allowing them to emit radiation that reveals their position within the crystal.
