New Topological Insulator Paves Way for Light-Matter Interaction Between Systems
WÜRZBURG, Germany, Oct. 17, 2018 — An international research team has built a topological insulator that can operate with light and electronic excitations simultaneously. Existing topological insulators are based on either electrons or photons, allowing only one of these applications to be implemented. In contrast, the new system, developed by physicists at Julius-Maximilians-Universität Würzburg (JMU), with colleagues from the Technion-Israel Institute of Technology and Nanyang Technological University, can be used for both...
