Theory of optical spectral weights in Mott insulators with orbital degrees of freedom
Giniyat Khaliullin, Peter Horsch, Andrzej M. Oles
Introducing partial sum rules for the optical multiplet transitions, we outline a unified approach to magnetic and optical properties of strongly correlated transition metal oxides…
