Nature Physics, Published online: 26 June 2026; doi:10.1038/s41567-026-03340-1 The electronic structure of materials can be tailored using pulses of light, and through this so-called Floquet engineering, novel materials can be designed. Now, the technique has been used to create light-induced metallic surface states in the band gap of a semiconductor — transforming the material, transiently, into…
Looks like Mother Nature knows how to cook these things way before many of us know about it. Newly-found samples of kawazulite found in gold mines in the Czech Republic shows properties of being a topological insulator , and may in fact have a higher quality than made-made ones. In search of materials that display these properties, Gehring and his
colleagues examined a natural sample of kawazuli…
