“Screw this!” – Spiral dislocation gives 3D topological photonics a robust edge

Successful international collaboration has substantially advanced fundamental research on topological photonics

30-Sep-2022

Researchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering. Their ...

Laser takes pictures of electrons in crystals

The experiments pave the way towards to deeply understand and eventually control the chemical and the electronic properties of materials

03-Jul-2020

Microscopes of visible light allow us to see tiny objects such living cells and their interior. Yet, they cannot discern how electrons are distributed among atoms in solids. Now researchers around Prof. Eleftherios Goulielmakis of the Extreme Photonics Labs at the University of Rostock and the ...

Taking the temperature of the periodic system

05-May-2020

It took almost a century until the spectral lines, first discovered by William H. Wollaston and Joseph von Fraunhofer at the onset of the 19th century, were explained by Niels Bohr with his famous atomic model. Quantum mechanics then provided the tools to calculate the atomic spectral lines of ...

Added Disorder Drives Transition to Photonic Topological Insulator

28-Aug-2018

As the journal Nature reported recently, a research group led by the Rostock physicist Professor Alexander Szameit, in collaboration with colleagues in Israel and the U.S., experimentally demonstrated that a messy topological insulator can be restored in its properties by inducing random ...

X-ray pulses uncover free nanoparticles for the first time in 3-D

'Super microscope' reveals unexpected variety of shapes

10-Feb-2015

For the first time, a German-American research team has determined the three-dimensional shape of free-flying silver nanoparticles, using DESY's X-ray laser FLASH. The tiny particles, hundreds of times smaller than the width of a human hair, were found to exhibit an unexpected variety of shapes, ...

Cool it, quick: Rapid cooling leads to stronger alloys

Researchers reveal a new technique to produce high strength metallic alloys, at a lower cost using less energy

11-Jul-2013

A team of researchers from the University of Rostock in Germany has developed a new way to rapidly produce high strength metallic alloys, at a lower cost using less energy than before. It's expected that this breakthrough will profoundly change how we produce components used in a diverse range of ...
