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…

SPRING: an effective and reliable framework for image reconstruction in single-particle Coherent Diffraction Imaging
Alessandro Colombo, Mario Sauppe, Andre Al Haddad +40
Coherent Diffraction Imaging (CDI) is an experimental technique to gain images of isolated structures by recording the light scattered off the sample. In principle, the sample dens…
