Non-linear X-ray Coherent Diffractive Imaging
Arnab Sarkar, Allan S. Johnson
The advent of nonlinear X-ray processes like sum-frequency generation and four-wave mixing raises the possibility of non-linear X-ray imaging, combining the high-resolution and ele…

Coherent X-ray Imaging of Stochastic Dynamics
Arnab Sarkar, Allan S. Johnson
Condensed phase systems often exhibit a mixture of deterministic and stochastic dynamics at the nanoscale which are essential to understanding their function, but can be challengin…
