Ultrafast Suppression of the Ferroelectric Instability in KTaO
Viktor Krapivin, Mingqiang Gu, D. Hickox-Young +13
We use an x-ray free-electron laser to study the ultrafast lattice dynamics following above band-gap photoexcitation of the incipient ferroelectric potassium-tantalate, \kto. % We…
Ultrafast terahertz-field-driven ionic response in ferroelectric BaTiO
F. Chen, Y. Zhu, S. Liu +31
The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and function…
How to distinguish squeezed and coherent phonons in femtosecond x-ray diffuse scattering
T. Henighan, M. Trigo, M. Chollet +9
Impulsive optical excitation can generate both coherent and squeezed phonons. The expectation value of the phonon displacement oscillates at the mode frequency for the cohe…
Generation of high-frequency strain waves during femtosecond demagnetization of Fe/MgO films
T. Henighan, M. Trigo, S. Bonetti +22
We use femtosecond time-resolved hard x-ray scattering to detect coherent acoustic phonons excited during ultrafast laser demagnetization of bcc Fe films. We determine the lattice…
