Nanoscale heterogeneous dynamics probed by nanosecond x-ray speckle visibility spectroscopy
Yanwen Sun, Gabriella Carini, Matthieu Chollet +15
We report observations of nanosecond nanometer scale heterogeneous dynamics in a free flowing colloidal jet revealed by ultrafast x-ray speckle visibility spectroscopy. The nanosec…
Realizing split-pulse x-ray photon correlation spectroscopy to measure ultrafast dynamics in complex matter
Yanwen Sun, Mike Dunne, Paul Fuoss +5
Split-pulse x-ray photon correlation spectroscopy has been proposed as one of the unique capabilities made possible with the x-ray free electron lasers. It enables characterization…
Speckle correlation as a monitor of X-ray free electron laser induced crystal lattice deformation
Rajan Plumley, Yanwen Sun, Samuel W Teitelbaum +8
X-ray free electron lasers (X-FELs) present new opportunities to study ultrafast lattice dynamics in complex materials. While the unprecedented source brilliance enables high fidel…
Disentangling charge and structural contributions during coherent atomic motions studied by ultrafast resonant x-ray diffraction
L. Rettig, A. Caviezel, S. O. Mariager +20
We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing…
Direct Experimental Observation of the Gas Filamentation Effect using a Two-bunch X-ray FEL Beam
Y. Feng, D. W. Schafer, S. Song +6
We report the experimental observation of the filamentation effect in gas devices designed for X-ray Free-electron Lasers. The measurements were carried out at the Linac Coherent L…
Ultrafast energy and momentum resolved dynamics of magnetic correlations in photo-doped Mott insulator SrIrO
M. P. M. Dean, Yue Cao, X. Liu +32
Measuring how the magnetic correlations throughout the Brillouin zone evolve in a Mott insulator as charges are introduced dramatically improved our understanding of the pseudogap,…
