TL;DR: It is shown that the wave vector and frequency profiles of this x-ray analogue of coherent Raman spectroscopy provide an excellent real-space probe that carries most valuable structural and dynamical information, not available from spontaneous Raman techniques.

TL;DR: X-ray fluorescence spectroscopy with monochromatic photon excitation is presented as a tool for studies of charge-transfer excitations in correlated systems, using CeO {sub 2} and UO{sub 3} as examples.

TL;DR: In this article, high-energy resolution photoelectron spectra of graphite were measured at excitation energies of 340, 870, 5950, and $7940\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ using synchrotron radiation.

TL;DR: In this article, a systematic description of coherent ultrafast x-ray spectroscopies in terms of nonlinear response functions and susceptibilities is developed, where correlation-function expressions of charge and current densities provide a unified treatment and classification of information content of the various possible techniques and connect them with their optical counterparts.

TL;DR: In this article, the decay process of the photoexcited 4f electron in the ground state of the Ce 4d\ensuremath{\rightarrow}4f photoabsorption region was investigated by means of a resonant photoemission technique.
