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…

Direct observation of the exciton polaron by serial femtosecond crystallography on single CsPbBr quantum dots
Zhou Shen, Margarita Samoli, Onur Erdem +28
The outstanding opto-electronic properties of lead halide perovskites have been related to the formation of polarons. Nevertheless, the observation of the atomistic deformation bro…
