Multipeak quasielastic light scattering and high-frequency electronic excitations in honeycomb Li${}_2$RuO${}_3$

Yu. S. Ponosov, S. V. Streltsov

We measured the temperature dependence of low-frequency Raman spectra in Li${}_2$RuO${}_3$, and observed multipeak quasielastic scattering in the Ru honeycomb polarizations below and a…
