Hidden domain boundary dynamics towards crystalline perfection
A. Mangu, V. A. Stoica, H. Zheng +19
A central paradigm of non-equilibrium physics concerns the dynamics of heterogeneity and disorder, impacting processes ranging from the behavior of glasses to the emergent function…
Critical slowing of the spin and charge density wave order in thin film Cr following photoexcitation
Sheena K. K. Patel, Oleg Yu. Gorobtsov, Devin Cela +11
We report on the evolution of the charge density wave (CDW) and spin density wave (SDW) order of a chromium film following photoexcitation with an ultrafast optical laser pulse. Th…
Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO and KTaO
Yijing Huang, Peihao Sun, Samuel W. Teitelbaum +21
We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe sca…
Charge Density Wave bending observed by Xfel source acting as a tunable electronic lens for hard x-rays
E. Bellec, D. Ghoneim, A. Gallo +6
Ultrafast X-ray diffraction by the LCLS free-electron laser has been used to probe Charge Density Wave (CDW) systems under applied external currents. At sufficiently low currents,…
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…
