Ultrafast and coupled – atomic vibrations in the quantum material boron nitride  
Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental…  
Thomas Elsaesser receives the Ahmed Zewail Award for Ultrafast Science and Technology from the American Chemical Society  
The American Chemical Society (ACS) has awarded Thomas Elsaesser the Ahmed Zewail Award 2022. The prize is named after Ahmed Zewail, a pioneer of ultrafast science and Nobel Prize winner in…  
Tracking down antiferromagnets  
Antiferromagnets are magnetically ordered, but their magnetization exactly cancels out. That is why even their discoverer, Nobel laureate Louis Néel, could not imagine any application for this class…  
Light tailored graphene for quantum technology  
All electronic devices around us, including the one you are using to read this, utilize the charge of an electron for storing and processing information. All operations performed by these electronic…  
Technicolor X-ray Images  
X-rays are a powerful tool for imaging objects. X-ray microscopes provide the ability to penetrate through matter and to resolve tiny features that remain hidden with visible light. Typically, X-ray…  
Honey, we shrunk the intense XUV laser  
An international team of researchers has demonstrated a new concept for the generation of intense extreme-ultraviolet (XUV) radiation by high-harmonic generation (HHG). Its advantage lies in the fact…  
A New Light on Quantum Science  
A research team of the Institute of Physics of the Humboldt University of Berlin together with cooperation partners Max Born Instituts (Berlin) and DLR Institute of Optical Sensor Systems…  
Shaken, not stirred: Reshuffling Skyrmions Ultrafast  
Smaller, faster, more energy-efficient: future requirements to computing and data storage are hard to fulfill and alternative concepts are continuously explored. Small magnetic textures, so-called…  
When Functional Materials Become Squishy  
Most people associate terahertz radiation from airport scanners. These radiations can, however, unleash a bag full of surprises when used to interrogate novel materials. An international team of…  
Topological protection versus degree of entanglement of two-photon light in photonic topological insulators  
In a joint effort, researchers from the Humboldt-Universität (Berlin), the Max Born Institute (Berlin) and the University of Central Florida (USA), have revealed the necessary conditions for the…
