Journal ArticleDOI
Multidimensional Attosecond Resonant X-Ray Spectroscopy of Molecules: Lessons from the Optical Regime
TL;DR: It is discussed possible experiments that employ attosecond X-ray pulses to probe the quantum coherence and correlations of valence electrons and holes, rather than the charge density alone, building on the analogy with existing studies of vibrational motions using femtosecond techniques in the visible regime.
Journal ArticleDOI
Core and valence excitations in resonant X-ray spectroscopy using restricted excitation window time-dependent density functional theory.
TL;DR: Comparison of the simulated XANES signals with experiment shows that the restricted window time-dependent density functional theory is more accurate and computationally less expensive than the static exchange method.
Journal ArticleDOI
Communication: Comment on the effective temporal and spectral resolution of impulsive stimulated Raman signals
Shaul Mukamel,Jason D. Biggs +1 more
TL;DR: It is shown that even though the external spectral and temporal parameters of the pulses may be independently controlled, the effective temporal and spectral resolution of the experiment may not exceed the fundamental bandwidth limitation.
Journal ArticleDOI
Two-dimensional stimulated resonance Raman spectroscopy of molecules with broadband x-ray pulses.
TL;DR: In this paper, expressions for the 2D-SXRS signal obtained using attosecond x-ray pulses are derived for trans-N-methyl acetamide (NMA) with broad bandwidth (181 as, 14.2 eV FWHM) pulses tuned to the oxygen and nitrogen K-edges.
Journal ArticleDOI
Two-Dimensional Stimulated Resonance Raman Spectroscopy of Molecules with Broadband X-ray Pulses
TL;DR: Crosspeaks in 2D signals reveal electronic Franck-Condon overlaps between valence orbitals and relaxed orbitals in the presence of the core-hole.
