A novel topological insulator

For the first time, physicists have built a unique topological insulator in which optical and electronic excitations hybridize and flow together. They report their discovery in Nature.

Achieving zero resistance in energy flow

Laptop computer users operating their devices on their laps will be familiar with the heat they generate, which comes from electrical resistance converting waste energy to heat. Scientists dream of creating electronic devices ...

New electricity grids possible with computer simulations

Renewable energy requires new electricity grids, sometimes over entire continents, because 'green energy' is often generated in remote locations. A general problem in such networks is that, although electrically conductive ...

Insulating bricks with microscopic bubbles

The better a building is insulated, the less heat is lost in winter—and the less energy is needed to achieve a comfortable room temperature. The Swiss Federal Office of Energy (SFOE) regularly raises the requirements for ...

Limitation exposed in promising quantum computing material

Quantum computers promise to perform operations of great importance believed to be impossible for our technology today. Current computers process information via transistors carrying one of two units of information, either ...
