Unified approach to time-resolved x-ray and electron diffraction imaging
Mingrui Yuan, Nikolay V. Golubev
Time-resolved x-ray diffraction (TR-XRD) and ultrafast electron diffraction (TR-UED) are emerging tools for probing ultrafast quantum dynamics. From a theoretical perspective, they…

Control of valence-electron motion in Xe cations using the stimulated-Raman-adiabatic-passage technique
Miguel A. Alarcón, Karl Hauser, Nikolay V. Golubev
This work theoretically investigates possibilities of using the Stimulated Raman Adiabatic Passage (STIRAP) and its variants to control a coherent superposition of quantum states.…

Can increasing the size and flexibility of a molecule reduce decoherence and prolong charge migration?
Alan Scheidegger, Nikolay V. Golubev, Jiri J. L. Vanicek
Coherent superposition of electronic states, created by ionizing a molecule, can initiate ultrafast dynamics of the electron density. Correlation between nuclear and electron motio…
