Sub-angstrom many-body localization driven by phononic flat bands in real quantum materials
Yingpeng Qi, Jianmin Yang, Zhihui Zhou +10
Defects, fluctuations, degenerate states and correlated interactions facilitate the emergence of exotic properties in condensed matter systems while also inducing atomic-scale loca…
Electronic excitation of ultrafast collective amorphous-amorphous transitions in glassy phase-change material
Yingpeng Qi, Nianke Chen, Zhihui Zhou +10
The intrinsic nature of glass states and glass transitions remain a fundamental open question in condensed-matter physics and materials science. The key to solving the glass transi…
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…
