Nonlinear phenomena in X-ray fluorescence from single nanoparticles under extreme conditions
Sebastian Cardoch, Tamme Wollweber, Sarodi Jonak Dutta +26
Materials exposed to intense femtosecond X-ray pulses with energies above their K-shell absorption edge can enter an extremely ionized state, which could give rise to nonlinear phe…

Single-particle incoherent diffractive imaging and amplified spontaneous emission in copper nanocubes
Tamme Wollweber, Sarodi Jonak Dutta, Zhou Shen +26
We demonstrate element-specific incoherent diffractive imaging (IDI) of single copper nanocubes using intensity correlations of K fluorescence at a hard X-ray free-electron las…

Convergent-beam attosecond X-ray crystallography
Henry N. Chapman, Chufeng Li, Saša Bajt +17
Sub-angstrom spatial resolution of electron density coupled with sub-femtosecond temporal resolution is required to directly observe the dynamics of the electronic structure of a m…
