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…
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…
Photoinduced ultrafast transition of the local correlated structure in chalcogenide phase-change materials
Yingpeng Qi, Nianke Chen, Thomas Vasileiadis +4
Revealing the bonding and time-evolving atomic dynamics in functional materials with complex lattice structures can update the fundamental knowledge on rich physics therein, and al…
Traversing double-well potential energy surfaces: photoinduced concurrent intralayer and interlayer structural transitions in XTe2 (X=Mo, W)
Yingpeng Qi, Mengxue Guan, Daniela Zahn +6
Manipulating crystal structure and the corresponding electronic properties in quantum materials provides opportunities for the exploration of exotic physics and practical applicati…
Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet
Daniela Zahn, Florian Jakobs, Yoav William Windsor +8
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopi…
Accessing the anisotropic non-thermal phonon populations in black phosphorus
Hélène Seiler, Daniela Zahn, Marios Zacharias +8
We combine femtosecond electron diffuse scattering experiments and first-principles calculations of the coupled electron-phonon dynamics to provide a detailed momentum-resolved pic…
Anisotropic Nonequilibrium Lattice Dynamics of Black Phosphorus
Daniela Zahn, Patrick-Nigel Hildebrandt, Thomas Vasileiadis +4
Black phosphorus has recently attracted significant attention for its highly anisotropic properties. A variety of ultrafast optical spectroscopies has been applied to probe the car…
