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.…
Quantum attomicroscopy: imaging quantum chemistry in action
Nikolay V. Golubev, Mohammed Th. Hassan
How quantum electron and nuclei motions affect biomolecular chemical reactions remains a central challengeable question at the interface of quantum chemistry and biology. Ultrafast…
Attosecond Transient Absorption Study of Coherent Hole Oscillation in Ar+
Nisnat Chakraborty, Miguel Alarcon, Michael P. McDonnell +6
We report on the observation, characterization, and control of the electron dynamics in ionized argon atoms. We utilized an intense mid-infrared (MIR) pulse to create a coherent su…
Comment on "Comment on Attosecond electron microscopy and diffraction"
Dandan Hui, Husain Alqattan, Mohamed Sennary +2
Over the past few decades, following the first demonstration of ultrafast electron microscopy, numerous research groups have focused on achieving attosecond temporal resolution in…
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…
