We propose a theory of two-magnon Raman scattering from the insulating parent compounds of high-{ital T}{sub {ital c}} superconductors, which contains information not only on magnetism, but also on the electronic properties in these materials. We use spin-density-wave formalism for the Hubbard model, and study diagrammatically the profile of the two-magnon scattering and its intensity dependence on the incoming photon frequency {omega}{sub {ital i}} both for {omega}{sub {ital i}}{much_lt}{ital…

Magnetic-order induced effects in nanocrystalline NiO probed by Raman spectroscopy
The magnetic-order induced effects in nanocrystalline NiO are investigated through the phonons and magnons observed in the Raman spectra. The key observations are (i) an anisotropy of the first-order
Spin-wave theory of two-magnon Raman scattering in iron Pnictides and Chalcogenides
Abstract Motivated by the experimental measurement of the two-magnon Raman scattering in iron Pnictides and Chalcogenides superconductors (Okazaki et al., 2011; Sugai et al., 2012), the underlying
Non-resonant Raman scattering through a metal-insulator transition: an exact analysis of the Falicov-Kimball model
For years, theories for Raman scattering have been confined to either the insulating or fully metallic state. While much can be learned by focusing attention on the metal or insulator, recent
One-gap scenario to explain Raman scattering in a d -wave superconductor
Recent Raman scattering data in B{sub 1g} and B{sub 2g} geometries in the superconducting state of underdoped cuprates were interpreted as evidence for two distinct energy gaps. We argue that these
Electronic Raman scattering in correlated materials : A treatment of nonresonant, mixed, and resonant scattering using dynamical mean-field theory
We solve for the electronic Raman scattering response functions on an infinite-dimensional hypercubic lattice employing dynamical mean field theory. This contribution extends previous work on the
Excitons in the upper Hubbard band
Motivated by recent Raman and resonant inelastic X-ray scattering experiments performed for Mott insulators, which suggest existence of excitons in these systems, we present a theory of exciton
Inelastic light scattering from correlated electrons
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
Resonant A 1 phonon and four-magnon Raman scattering in hexagonal HoMnO 3 thin film
We present the results of resonant Raman scattering of the A1 phonon at 680 cm−1 and of the four-magnon at 760 cm−1 in hexagonal HoMnO3 thin film. We find that the A1 phonon at 680 cm−1 shows a
optical absorption data; comparison with the results of neutron and muon experiments
Narrow-band spectral features demonstrating a high sensitivity to the development of the pseudogap state are detected in metallic films of YBa2Cu3O6+x with Tc≈51 and 74 K. Attention is focused on the
Electronic Raman scattering through a stripe ordering transition in La2−xSrxNiO4
We describe the results of electronic Raman scattering experiments in two differently doped single crystals of La2−xSrxNiO4 (x=0.225 and 1/3). In B1g symmetry a crossover from weakly interacting to
