Directly observing atomic-scale relaxations of a glass forming liquid using femtosecond X-ray photon correlation spectroscopy
Tomoki Fujita, Yanwen Sun, Haoyuan Li +25
Glass forming liquids exhibit structural relaxation behaviors, reflecting underlying atomic rearrangements on a wide range of timescales. These behaviors play a crucial role in det…
Structural changes across thermodynamic maxima in supercooled liquid tellurium: a water-like scenario
Peihao Sun, Giulio Monaco, Peter Zalden +10
Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K be…
Generation of highly mutually coherent hard x-ray pulse pairs with an amplitude-splitting delay line
Haoyuan Li, Yanwen Sun, Joan Vila-Comamala +11
Beam splitters and delay lines are among the key building blocks of modern-day optical laser technologies. Progress in x-ray free electron laser source development and applications…
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…
