Light-induced dimension crossover in 1T-TiSe dictated by excitonic correlations
Yun Cheng, Alfred Zong, Jun Li +18
In low-dimensional systems with strong electronic correlations, the application of an ultrashort laser pulse often yields novel phases that are otherwise inaccessible. The central…
Optical manipulation of electronic dimensionality in a quantum material
Shaofeng Duan, Yun Cheng, Wei Xia +9
Exotic phenomenon can be achieved in quantum materials by confining electronic states into two dimensions. For example, relativistic fermions are realised in a single layer of carb…
Achieving 50 femtosecond resolution in MeV ultrafast electron diffraction with a double bend achromat compressor
Fengfeng Qi, Zhuoran Ma, Lingrong Zhao +12
We propose and demonstrate a novel scheme to produce ultrashort and ultrastable MeV electron beam. In this scheme, the electron beam produced in a photocathode radio-frequency (rf)…
Non-Coulomb strong electron-hole binding in revealed by time- and angle-resolved photoemission spectroscopy
Tangwei Tang, Hongyuan Wang, Shafeng Duan +5
We reveal an ultrafast purely electronic phase transition in \TNS, which is a plausible excitonic insulator, after excited by an ultrafast infrared laser pulse. Specifically, the o…
