Geometry of intricately fabricated glass makes light trap itself

Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic ...

Topological insulators feature lossless conduction at the edges

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...

When predictions of theoretical chemists become reality

Thomas Heine, professor of theoretical chemistry at TU Dresden, together with his team, first predicted a topological 2-D polymer in 2019. Only one year later, an international team led by Italian researchers was able to ...

4-D electric circuit network with topology

In recent years, topology has emerged as an important tool to classify and characterize properties of materials. It has been found that many materials exhibit a number of unusual topological properties, which are unaffected ...

Quantum hall effect 'reincarnated' in 3-D topological materials

U.S. and German physicists have found surprising evidence that one of the most famous phenomena in modern physics—the quantum Hall effect—is "reincarnated" in topological superconductors that could be used to build fault-tolerant ...

New protocol identifies fascinating quantum states

Topological materials attract great interest and may provide the basis for a new era in materials development. In Science Advances, physicists around Andreas Elben, Jinlong Yu, Peter Zoller and Benoit Vermersch now present ...
