Exploring the Scientific Basis and Potential for Coherent X-Ray Spectroscopies Including X-Ray Coherent Anti-Stokes Raman Scattering

Abstract

Coherent spectroscopic or inelastic scattering techniques in the visible and infrared spectral regimes have been extensively exploited for probing chemical and biomolecular phenomena under chemically reactive, biologically active, and-or non-equilibrium conditions. These methods have been generally restricted to optically thin or interfacial systems. Coherent spectroscopies in the hard or tender X-ray regime, on the other hand, offer the potential to probe dynamical transformations of optically thick, dense media. New developments in coherent X-ray sources, such as X-ray free-electron lasers (XFELs), provide unprecedented opportunities for leveraging coherent X-ray spectroscopies and inelastic scattering methods for probing the dynamics of dense systems. We propose to investigate the scientific foundation for coherent light-matter interactions in the hard and tender X-ray regime. Our goal is to explore methods for exploiting these interactions for gaining new insight into chemical and phase transformations of reactive condensed phase materials. We propose to focus on experimental and theoretical investigations of the scientific foundation and potential for implementation of X-ray coherent anti-Stokes Raman scattering (XCARS) and stimulated X-ray Raman scattering (SXRS) in the tender and hard X-ray regime.
