Ultrafast X-ray Diffraction Probe of Coherent Spin-State Dynamics in Molecules [PDF]
The Journal of Physical Chemistry Letters, 2023 We propose an approach to probe coherent spin-state dynamics of molecules using circularly polarized hard x-ray pulses. For the dynamically aligned nitric oxide molecules in a coherent superposition spin-orbit coupled electronic state that can be prepared through stimulated Raman scattering, we demonstrate the capability of ultrafast x-ray diffraction ...

Magnetoacoustics observed with ultrafast x-ray diffraction
Review of Scientific Instruments, 2022 In der vorliegenden Arbeit untersuche ich die Gitterdynamik von magnetisch geordneten und dünnen Filmen, deren Spinsystem mit Femtosekunden-Laserpulsen angeregt und untersucht wird. Die Quantifizierung der laserinduzierten thermischen Dynamik, der erzeugten Pikosekunden-Schallpulse sowie deren jeweiliger Einfluss auf die Magnetisierungsdynamik ist ein ...

Monitoring nonadiabatic dynamics in molecules by ultrafast X-Ray diffraction [PDF]
EPJ Web of Conferences, 2019 We theoretically examine time-resolved diffraction from molecules which undergo non-adiabatic dynamics and identify contributions from inelastic scattering that indicate the presence of an avoided crossing and the corresponding nuclear configuration.

A Highly Stable-Output Kilohertz Femtosecond Hard X-ray Pulse Source for Ultrafast X-ray Diffraction
Applied Sciences, 2022 Femtosecond hard X-ray pulses generated by laser-driven plasma sources are eminently suitable to probe structural dynamics due to the angstrom spatial resolution and sub-picosecond time resolution. However, the insufficient flux of X-ray photons and high
