Computational XPCS

Shaswat Mohanty

X-ray photon correlation spectroscopy (XPCS) is a powerful experimental technique used to characterize the material dynamics across awide range of length scales and time scales. The method captures the dynamics from scattering intensity fluctuations captured by individual X-ray pulses. By looking at different detector points, we can access dynamics at different length scales, and by changing the delay between X-ray pulses, we can access the dynamics at different time scales.
 

We develop a computation XPCS (C-XPCS) code to carry out the XPCS and X-ray speckle visibility spectroscopy (XSVS) experiments from molecular dynamics trajectories.
