Raman scattering in a Heisenberg {\boldmath $S=1/2$} antiferromagnet on the triangular lattice

Natalia Perkins, Wolfram Brenig

We investigate two-magnon Raman scattering from the $S=1/2$ Heisenberg antiferromagnet on the triangular lattice, considering both the effect of renormalization of the one-magnon s…
