The capability to probe the dispersion of elementary spin, charge, orbital, and lattice excitations has positioned resonant inelastic x-ray scattering (RIXS) at the forefront of photon science. Here we develop the scattering theory for RIXS on superconductors, calculating its momentum-dependent scattering amplitude. Considering superconductors with different pairing symmetries, we show that the low-energy scattering is strongly affected by the superconducting gap and coherence factors. This…

Theoretical approach to resonant inelastic x-ray scattering in iron-based superconductors at the energy scale of the superconducting gap
TLDR
The results show that RIXS spectra can distinguish between s± and s++ wave gap functions in the singlet pairing case and an analogous intensity redistribution at small momenta can reveal the presence of a chiral p-wave triplet pairing.
Probing the energy gap of high-temperature cuprate superconductors by resonant inelastic x-ray scattering
The determination of the symmetry of the energy gap is crucial for research on the microscopic mechanisms of unconventional superconductivity. Here, we demonstrate experimentally that high-resolution
Insights into the high temperature superconducting cuprates from resonant inelastic X-ray scattering
Abstract Recent improvements in instrumentation have established resonant inelastic X-ray scattering (RIXS) as a valuable new probe of the magnetic excitations in the cuprates. This paper introduces
Indirect K-edge bimagnon resonant inelastic x-ray scattering spectrum of α-FeTe.
TLDR
The predicted RIXS spectrum can be utilized to understand the role of multi-channel bimagnon spin excitations present in the α-FeTe chalcogenide, which is sensitive to next-next nearest neighbor and biquadratic coupling interactions.

Probing Hidden Orders with Resonant Inelastic X-Ray Scattering
We propose a general scheme for the derivation of the signals resonant inelastic (and elastic) x-ray scattering (RIXS) gives access to. In particular, we find that RIXS should allow to directly
Propagation and Scattering of High-Intensity X-Ray Pulses in Dense Atomic Gases and Plasmas
Nonlinear spectroscopy in the x-ray domain is a promising technique to explore the dynamics of elementary excitations in matter. X-rays provide an element specificity that allows them to target
Theory of fluctuating charge ordering in the pseudogap phase of cuprates via a preformed pair approach
We study the static and dynamic behavior of charge ordering within a d-wave pair pseudogap (pg) scenario. This is addressed using a density-density correlation function derived from the standard pg

In this chapter, I describe the RIXS technique for the study of electronic excitations in strongly correlated copper oxides from experimental point of view.
