WebThis dramatic spectral weight transfer is believed to be a signature of the strong electronic correlations in these and related materials [3]. The use of sum rules in optical conductivity measure-ments has had a wide impact in a number of ﬁelds of science. The optical sum rule originated in atomic physics WebThe spectral weight further decreases and almost disappears at half-ﬁlling [Figs. 1(e)–1(h)]. As for k⊥ = π, the dominant mode in the low-electron-density regime [Fig. 1(i)] gradually loses spectral weight with the electron density [Figs. 1(j)–1(o)] and completely disappears at half-ﬁlling [Fig. 1(p)]. Instead, because of the sum ...
