Generation of Intense Phase-Stable Femtosecond Hard X-ray Pulse Pairs
Yu Zhang, Thomas Kroll, Clemens Weninger +24
Coherent nonlinear spectroscopies and imaging in the X-ray domain provide direct insight into the coupled motions of electrons and nuclei with resolution on the electronic length a…
Double Core Hole Valence-to-Core X-ray Emission Spectroscopy: A Theoretical Exploration Using Time-Dependent Density Functional Theory
Yu Zhang, Uwe Bergmann, Robert W. Schoenlein +2
With the help of newly developed X-ray free-electron laser (XFEL) sources, creating double core holes simultaneously at the same or different atomic sites in a molecule has now bec…
Time-, Frequency-, and Wavevector-Resolved X-Ray Diffraction from Single Molecules
Kochise Bennett, Jason D. Biggs, Yu Zhang +2
Using a quantum electrodynamic framework, we calculate the off-resonant scattering of a broad-band X-ray pulse from a sample initially prepared in an arbitrary superposition of ele…
Nonlinear light scattering in molecules triggered by an impulsive X-ray Raman process
Konstantin E. Dorfman, Kochise Bennett, Yu Zhang +1
The time-and-frequency resolved nonlinear light scattering (NLS) signals from a time evolving charge distribution of valence electrons prepared by impulsive X-ray pulses are calcul…
Double-core Excitations in Formamide Can Be Probed by X-ray Double-quantum-coherence Spectroscopy
Yu Zhang, Daniel Healion, Jason D. Biggs +1
The attosecond, time-resolved X-ray double-quantum-coherence (XDQC) four wave mixing signals of formamide at the nitrogen and oxygen K-edges are simulated using restricted excitati…
Multidimensional X-Ray Spectroscopy of Valence and Core Excitations in Cysteine
Jason D. Biggs, Yu Zhang, Daniel Healion +1
Several nonlinear spectroscopy experiments which employ broadband x-ray pulses to probe the coupling between localized core and delocalized valence excitation are simulated for the…
Two-Dimensional Stimulated Resonance Raman Spectroscopy of Molecules with Broadband X-ray Pulses
Jason D. Biggs, Yu Zhang, Daniel Healion +1
Expressions for the two-dimensional Stimulated x-ray Raman Spectroscopy (2D-SXRS) signal obtained using attosecond x-ray pulses are derived. The 1D- and 2D-SXRS signals are calcula…
