Dual-stage structural response to quenching charge order in magnetite
Wei Wang, Junjie Li, Lijun Wu +8
The Verwey transition in magnetite (Fe3O4 ) is the prototypical metal-insulator transition and has eluded a comprehensive explanation for decades. A major element of the challenge…
Rehybridization dynamics into the pericyclic minimum of an electrcyclic reaction imaged in real-time
Yusong Liu, David M. Sanchez, Matthew R. Ware +17
Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transiti…
Applying Bayesian Inference and deterministic anisotropy to retrieve the molecular structure distribution from gas-phase diffraction experiments
Kareem Hegazy, Varun Makhija, Phil Bucksbaum +12
Currently, our general approach to retrieving molecular structures from ultrafast gas-phase diffraction heavily relies on complex ab initio electronic or vibrational excited state…
Large Itinerant Electron Exchange Coupling in the Magnetic Topological Insulator MnBi2Te4
Hari Padmanabhan, Vladimir A. Stoica, Peter Kim +20
Magnetism in topological materials creates phases exhibiting quantized transport phenomena with applications in spintronics and quantum information. The emergence of such phases re…
Direct visualization of ultrafast lattice ordering triggered by an electron-hole plasma in 2D perovskites
Hao Zhang, Wenbin Li, Joseph Essman +18
Direct visualization of ultrafast coupling between charge carriers and lattice degrees of freedom in photo-excited semiconductors has remained a long-standing challenge and is crit…
Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
Panoramic mapping of phonon transport from ultrafast electron diffraction and machine learning
Zhantao Chen, Xiaozhe Shen, Nina Andrejevic +11
One central challenge in understanding phonon thermal transport is a lack of experimental tools to investigate mode-based transport information. Although recent advances in computa…
Verwey transition as evolution from electronic nematicity to trimerons via electron-phonon coupling
Wei Wang, Jun Li, Zhixiu Liang +13
Understanding the driving mechanisms behind metal-insulator transitions (MITs) is a critical step towards controlling material's properties. Since the proposal of charge-order-indu…
