Terahertz-driven Local Dipolar Correlation in a Quantum Paraelectric
Bing Cheng, Patrick L. Kramer, Zhi-Xun Shen +1
Light-induced ferroelectricity in quantum paraelectrics is a new avenue of achieving dynamic stabilization of hidden orders in quantum materials. In this work, we explore the possi…
Ultrafast x-ray scattering reveals composite amplitude collective mode in the Weyl charge density wave material (TaSe)I
Quynh L. Nguyen, Ryan A. Duncan, Gal Orenstein +27
We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe)I following photoexcitation with femtosecond infrared laser pulses…
The Persistence of Memory in Ionic Conduction Probed by Nonlinear Optics
Andrey D. Poletayev, Matthias C. Hoffmann, James A. Dawson +4
Predicting practical rates of ion transport from atomistic descriptors enables the rational design of materials, devices, and processes, which is especially critical to developing…
Ultrafast electron dynamics in platinum and gold thin films driven by optical and terahertz fields
Vivek Unikandanunni, Matthias C. Hoffmann, Paolo Vavassori +2
We investigate the ultrafast electron dynamics triggered by terahertz and optical pulses in thin platinum and gold films by probing their transient optical reflectivity. The respon…
Ultrafast modification of the electronic structure of a correlated insulator
O. Grånäs I. Vaskivskyi, X. Wang, P. Thunström +25
A non-trivial balance between Coulomb repulsion and kinematic effects determines the electronic structure of correlated electron materials. The use electromagnetic fields strong en…
Distinguishing Local and non-Local Demagnetization in Ferromagnetic FePt Nanoparticles
Patrick W. Granitzka, Alexander H. Reid, Jerome Hurst +21
Time-resolved coherent X-ray diffraction is used to measure the spatially resolved magnetization structure within FePt nanoparticles during laser-induced ultrafast demagnetization.…
