Structural contribution to light-induced gap suppression in TaNiSe
Zijing Chen, Chenhang Xu, Chendi Xie +13
An excitonic insulator is a material that hosts an exotic ground state, where an energy gap opens due to spontaneous condensation of bound electron-hole pairs. TaNiSe is a…
Super-resolution femtosecond electron diffraction reveals electronic and nuclear dynamics at conical intersections
Hui Jiang, Juanjuan Zhang, Tianyu Wang +9
Conical intersections play a pivotal role in excited-state quantum dynamics. Capturing transient molecular structures near conical intersections remains challenging due to the rapi…
Probing valence electron and hydrogen dynamics using charge-pair imaging with ultrafast electron diffraction
Tianyu Wang, Hui Jiang, Ming Zhang +5
A key challenge in ultrafast science has been to directly track the coupled motions of electrons and nuclei in real-space and real-time. This study presents a significant step towa…
Imaging the photochemical dynamics of cyclobutanone with MeV ultrafast electron diffraction
Tianyu Wang, Hui Jiang, Cheng Jin +5
We study the photoinduced chemical dynamics of cyclobutanone upon excitation at 200 nm to the 3s Rydberg state using MeV ultrafast electron diffraction (UED). We observe both the e…
Ultrafast formation of topological defects in a 2D charge density wave
Yun Cheng, Alfred Zong, Lijun Wu +13
Topological defects play a key role in nonequilibrium phase transitions, ranging from birth of the early universe to quantum critical behavior of ultracold atoms. In solids, transi…
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…
Stable and scalable multistage terahertz-driven particle accelerator
Heng Tang, Lingrong Zhao, Pengfei Zhu +8
Particle accelerators that use electromagnetic fields to increase a charged particle's energy have greatly advanced the development of science and industry since invention. However…
