Inelastic light scattering is an intensively used tool in the study of electronic properties of solids. Triggered by the discovery of high-temperature superconductivity in the cuprates and by new developments in instrumentation, light scattering in both the visible (Raman effect) and x-ray part of the electromagnetic spectrum has become a method complementary to optical (infrared) spectroscopy while providing additional and relevant information. The main purpose of the review is to position… 
Resonant Inelastic X-ray Scattering Studies of Elementary Excitations
In the past decade, resonant inelastic x-ray scattering (RIXS) has made remarkable progress as a spectroscopic technique. This is a direct result of the availability of high-brilliance synchrotron
Development of a graphite polarization analyzer for resonant inelastic x-ray scattering.
TLDR
A new diffraction-based polarization analyzer which discriminates between linear polarization components of the scattered photons is reported which was designed as a good compromise between energy resolution and throughput.
Q-dependent light scattering by electrons in LaB6
The inelastic light scattering by intraband electronic excitations in metallic lanthanum hexaboride has been studied in the temperature range of 10–300 K. General agreement has been obtained between
Response, Relaxation and Transport in Unconventional Superconductors
Abstract We investigate the collision-limited electronic Raman response and the attenuation of ultrasound in spin-singlet d-wave superconductors at low temperatures. The dominating elastic collisions
Using RIXS to uncover elementary charge and spin excitations
Despite significant progress in resonant inelastic x-ray scattering (RIXS) experiments on cuprates at the Cu L-edge, a theoretical understanding of the cross-section remains incomplete in terms of
An electron-boson glue function derived from electronic Raman scattering.
TLDR
The newly measured Raman response data have been inverted using a modified maximum entropy inversion technique to extract from B(1g) and B(2g) Raman data corresponding electron-boson spectral densities (glue), and it is found that the B( 2g) spectrum agrees qualitatively with nodal direction ARPES while the B-1g results look more like the optical spectrum.
Controlling inelastic light scattering quantum pathways in graphene
TLDR
This study reveals quantum interference between different Raman pathways in graphene: when some of the pathways are blocked, the one-phonon Raman intensity does not diminish, as commonly expected, but increases dramatically, which sheds new light on the understanding of resonance Raman scattering in graphene.
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
Fluctuations and pairing in Fe-based superconductors: light scattering experiments.
TLDR
This work focuses on electronic and spin excitations in Fe-based pnictides and chalcogenides, in particular but not exclusively superconductors, and examines the response of particle-hole excitations to elastic scattering of visible light.

Raman spectrum of superconducting oxides.
TLDR
A surprising proportionality between the Raman line shape and the optical conductivity is derived in the nesting approximation, and similar electronic spectra should appear in other metals with nested Fermi surfaces, such as chromium and various rare-earth metals.

TLDR
The polarizations of the incident and scattered light enter the expressions of the scattering probability, thus giving a natural explanation for the intensity difference of the gap peaks in the A and E modes observed in experiments by Sooryakumar and Klein on 2H-NbSe/sub 2/.
