Dirac state manipulation by surface charge doping
In a paper published in Nano Letters , we show how chemisorption of potassium on BaNiS2 can tune Dirac bands in reciprocal space at the surface (J. Zhang, T. Sohier, …

Topological insulators under ultrafast light
The electronic structure of prototype topological insulators has been studied with ultrafast ARPES, using the ARTOF spectrometer in combination with the femtosecond laser source at the LPS. Using time-resolved multi-dimensional …
Tuning Dirac cones in BaNiS2
Dirac fermions play a central role in the physics of topological materials. We have shown for the first time that the properties of Dirac cones can be varied in reciprocal …
