X-ray induced electron and ion fragmentation dynamics in IBr

Phay J. Ho, Dipanwita Ray, Stefan Lehmann +9

Characterization of the inner-shell decay processes in molecules containing heavy elements is key to understanding x-ray damage of molecules and materials and for medical applicati…

Resonant Double-Core Excitations with Ultrafast, Intense Pulses

Adam E. A. Fouda, Dimitris Koulentianos, Linda Young +2

Intense few-to-sub-femtosecond soft x-ray pulses can produce neutral, two-site excited double-core-hole states by promoting two core electrons to the same unoccupied molecular orbi…

Enhanced ultrafast X-ray diffraction by transient resonances

Stephan Kuschel, Phay J. Ho, Andre Al Haddad +15

Diffraction-before-destruction imaging with single ultrashort X-ray pulses has the potential to visualise non-equilibrium processes, such as chemical reactions, at the nanoscale wi…

Ghost-imaging-enhanced non-invasive spectral characterization of stochastic x-ray free-electron-laser pulses

Kai Li, Joakim Laksman, Tommaso Mazza +8

High-intensity ultrashort X-ray free-electron laser (XFEL) pulses are revolutionizing the study of fundamental nonlinear x-ray matter interactions and coupled electronic and nuclea…

Fluorescence intensity correlation imaging with high resolution and elemental contrast using intense x-ray pulses

Phay J. Ho, Christopher J. Knight, Linda Young

We theoretically investigate the fluorescence intensity correlation (FIC) of Ar clusters and Mo-doped iron oxide nanoparticles subjected to intense, femtosecond and sub-femtosecond…

Ultraintense, ultrashort pulse x-ray scattering in small molecules

Phay J. Ho, Adam E. A. Fouda, Kai Li +2

We examine x-ray scattering from an isolated organic molecule from the linear to nonlinear absorptiveregime. In the nonlinear regime, we explore the importance of both the elastic…
