Resonant two-magnon Raman scattering in antiferromagnetic insulators
Andrey V. Chubukov, David M. Frenkel
We propose a theory of two-magnon {\it resonant\/} Raman scattering from antiferromagnetic insulators, which contains information both on the magnetism and the carrier properties i…

Systematic 1/S study of the 2D Hubbard model at half-filling
A. V. Chubukov, K. A. Musaelian
The 2D Hubbard model is extended by placing 2S orbitals at each lattice site and studied in a systematic 1/S expansion. The 1/S results for the magnetic susceptibility and the spec…
