Theory of Electronic Raman Scattering in Nearly Antiferromagnetic Fermi Liquids

摘要

A theory of electronic Raman scattering in nearly antiferromagnetic Fermiliquids is constructed using the phenomenological electron-electron interactionintroduced by Millis, Monien, and Pines. The role of "hot spots" and theirresulting signatures in the channel dependent Raman spectra is highlighted, anddifferent scaling regimes are addressed. The effects of self consistency andvertex corrections are compared to a perturbative treatment of the interaction.The theory is then compared to Raman spectra taken in the normal state ofcuprate superconductors, and it is shown that many features of the symmetrydependent spectra can be explained by the theory. Remaining questions areaddressed.
