Extreme Terahertz Nonlinear Phononics by Coherence-Imprinted Control of Hybrid Order
Liang Luo, Avinash Khatri, Martin Mootz +12
Coherent control of quantum materials has progressed along two major fronts: nonlinear phononics, which reshapes lattices to induce emergent states, and Floquet engineering, which…
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…
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…
Femtosecond electron diffraction reveals local disorder and local anharmonicity in thermoelectric SnSe
Jingjun Li, Yingpeng Qi, Qing Yang +6
The microscopic arrangement of atoms and molecules is the determining factor in how materials behave and perform. Beyond the long-range periodicity, the local disorder with local s…
