Raman Scattering Signatures of Kitaev Spin Liquids in A${}_2$ IrO${}_3$ Iridates

J. Knolle, Gia-Wei Chern, D. L. Kovrizhin +2

We study theoretically the Raman scattering response $I(\omega )$ in the gapless quantum spin liquid phase of the Kitaev-Heisenberg model. The dominant polarization-independent contribut…
