"Resonant Inelastic X-ray Scattering from Insulating Cuprates"
In this talk I will give a general introduction to the technique of
inelastic x-ray scattering (IXS) and its use for measuring elementary
excitations in condensed matter. I will describe how resonance
techniques can be used to achieve (1) enhancement of the inelastic
cross section and (2) sensitivity to wave function symmetry. These
points will be illustrated with polarization-dependent spectra from
the High Tc parent insulators La2CuO4 and Sr2CuO2Cl2, and by their
interpretation in terms of symmetry-selection rules. I will conclude
with some general statements about the utility of IXS - and where
to go from here.
