X-ray diffractive imaging of controlled gas-phase molecules: Toward imaging of dynamics in the molecular frame

Thomas Kierspel, Andrew Morgan, Joss Wiese +25

We report experimental results on the diffractive imaging of three-dimensionally aligned 2,5-diiodothiophene molecules. The molecules were aligned by chirped near-infrared laser pu…

Femtosecond x-ray diffraction from an aerosolized beam of protein nanocrystals

Salah Awel, Richard A. Kirian, Max O. Wiedorn +22

We demonstrate near-atomic-resolution Bragg diffraction from aerosolized single granulovirus crystals using an x-ray free-electron laser. The form of the aerosol injector is nearly…

Diffractive Imaging of Coherent Nuclear Motion in Isolated Molecules

Jie Yang, Markus Guehr, Xiaozhe Shen +17

Observing the motion of the nuclear wavepackets during a molecular reaction, in both space and time, is crucial for understanding and controlling the outcome of photoinduced chemic…

Diffractive imaging of a molecular rotational wavepacket with femtosecond Megaelectronvolt electron pulses

Jie Yang, Markus Guehr, Theodore Vecchione +20

Imaging changes in molecular geometries on their natural femtosecond timescale with sub-Angstrom spatial precision is one of the critical challenges in the chemical sciences, since…

Spatially resolved ultrafast magnetic dynamics launched at a complex-oxide hetero-interface

M. Först, A. D. Caviglia, R. Scherwitzl +18

Static strain in complex oxide heterostructures has been extensively used to engineer electronic and magnetic properties at equilibrium. In the same spirit, deformations of the cry…

Irreversible transformation of ferromagnetic ordered stripe domains in single-shot IR pump - resonant X-ray scattering probe experiments

Nicolas Bergeard, Stefan Schaffert, Víctor López-Flores +21

The evolution of a magnetic domain structure upon excitation by an intense, femtosecond Infra-Red (IR) laser pulse has been investigated using single-shot based time-resolved reson…

Nonlinear lattice dynamics as a basis for enhanced superconductivity in YBa2Cu3O6.5

R. Mankowsky, A. Subedi, M. Först +13

THz-frequency optical pulses can resonantly drive selected vibrational modes in solids and deform their crystal structure. In complex oxides, this method has been used to melt elec…

Real-time manifestation of strongly coupled spin and charge order parameters in stripe-ordered nickelates via time-resolved resonant x-ray diffraction

Y. D. Chuang, W. S. Lee, Y. F. Kung +27

We investigate the order parameter dynamics of the stripe-ordered nickelate, LaSrNiO, using time-resolved resonant X-ray diffraction. In spite of distinct spi…
