Controlling electron spins by light

Topological insulators are considered a very promising material class for the development of future electronic devices. A research team at Helmholtz-Zentrum Berlin has discovered, how light can be used to alter the physical properties of the electrons in these materials. Their results have just been published by the renowned journal Physical Review X.
