Generation and Characterization of Surface-Attached Ultrathin Liquid Sheets for Grazing-Incidence X-ray Scattering
Yibo Wang, Daniel P. DePonte, Adi Natan
Capturing the ultrafast structural dynamics that occur at the solid-liquid interface is key to understanding adsorption, desorption, diffusion, and aggregation processes in catalys…
Real-Space Inversion and Super-Resolution of Ultrafast Scattering
Adi Natan
Ultrafast scattering using X-rays or electrons is an emerging method to obtain structure dynamics at the atomic length and time scales. However, directly resolving in real-space at…
Attosecond Coherent Electron Motion in Auger-Meitner Decay
Siqi Li, Taran Driver, Philipp Rosenberger +38
In quantum systems, coherent superpositions of electronic states evolve on ultrafast timescales (few femtosecond to attosecond, 1 as = 0.001 fs = 10^{-18} s), leading to a time dep…
Resolving Multiphoton Processes with High-Order Anisotropy Ultrafast X-ray Scattering
Adi Natan, Aviad Schori, Grace Owolabi +3
We present first results on ultrafast X-ray scattering of strongly driven molecular Iodine and analysis of high-order anisotropic components of the scattering signal, up to four-ph…
Disentangling the Sub-Cycle Electron Momentum Spectrum in Strong-Field Ionization
Nicholas Werby, Adi Natan, Ruaridh Forbes +1
Quantum calculations of tunneling in strong-field ionization (SFI) predict intricate momentum distributions due to sub-laser-cycle attosecond electron dynamics. These are obscured…
Characterizing multiphoton excitation using time-resolved X-ray scattering
Philip H. Bucksbaum, Matthew R. Ware, Adi Natan +2
Molecular iodine was photoexcited by a strong 800 nm laser, driving several channels of multiphoton excitation. The motion following photoexcitation was probed using time-resolved…

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…
Attosecond Transient Absorption Spooktroscopy: a ghost imaging approach to ultrafast absorption spectroscopy
Taran Driver, Siqi Li, Elio G. Champenois +38
The recent demonstration of isolated attosecond pulses from an X-ray free-electron laser (XFEL) opens the possibility for probing ultrafast electron dynamics at X-ray wavelengths.…
Tunable Isolated Attosecond X-ray Pulses with Gigawatt Peak Power from a Free-Electron Laser
Joseph Duris, Siqi Li, Taran Driver +31
The quantum mechanical motion of electrons in molecules and solids occurs on the sub-femtosecond timescale. Consequently, the study of ultrafast electronic phenomena requires the g…
Filming non-radiative population transfer: Time-resolved x-ray scattering near an avoided crossing
Matthew R. Ware, James M. Glownia, James P. Cryan +3
We show that time-resolved x-ray scattering from molecules prepared in a superposition of electronic states moving through an avoided crossing has new features not found in diffrac…
Probing ultrafast ππ*/nπ* internal conversion in organic chromophores via K-edge resonant absorption
T. J. A. Wolf, R. H. Myhre, J. P. Cryan +21
Organic chromophores with heteroatoms possess an important excited state relaxation channel from an optically allowed ππ* to a dark nπ*state. We exploit the element and site specif…
