Auger Resonant Raman Scattering in Strontium Compounds.

Resonant Raman scattering in O2

Raman scattering of molecular oxygen in the region of the Schumann–Runge absorption band system is calculated from first principles in the second order of perturbation theory in the interaction of photon–electron operator. Quantitative predictions are given for the cross sections for scattering of photons and a detailed comparison is made with available measurements. The behavior of Raman spect...

Resonant Raman scattering in antiferromagnets

Two-magnon Raman scattering provides important information about electronic correlations in the insulating parent compounds of high-Tc materials. Recent experiments have shown a strong dependence of the Raman signal in B1g geometry on the frequency of the incoming photon. We present an analytical and numerical study of the Raman intensity in the resonant regime. It has been previously argued by...

Symmetry-Forbidden Resonant Raman Scattering in Cu2O

Resonant Raman scattering in mercurate single crystals

We report resonant electronic Raman scattering in optimally doped single layer HgBa2CuO4+δ (Hg-1201) and trilayer HgBa2Ca2Cu3O8+δ (Hg-1223) single crystals. Analysis of the B1g and B2g channels in the superconducting state of Hg-1201 advocates for a gap having d-wave symmetry. In addition a resonant study B1g pair-breaking peak and the A1g peak suggests that the A1g peak is not directly related...

Resonant Raman scattering off neutral quantum dots

Resonant inelastic (Raman) light scattering off neutral GaAs quantum dots which contain a mean number, N = 42, of electron-hole pairs is computed. We find Raman amplitudes corresponding to strongly collective final states (charge-density excitations) of similar magnitude as the amplitudes related to weakly collective or single-particle excitations. As a function of the incident laser frequency ...
