Comment to the paper "In-plane spectral weight shift of charge-carriers in YBa2Cu3O(6.9)" by A. V. Boris et al., Science 304, p. 708 (2004)
A. F. Santander-Syro, N. Bontemps
Recently, A. V. Boris and colleagues claimed to deduce a decrease of intraband spectral weight (SW), and a transfer of SW from intraband to inter-band frequencies, when optimally-d…

Sum rules and energy scales in BiSrCaCuO
A. F. Santander-Syro, R. P. S. M. Lobo, N. Bontemps
From very high accuracy reflectivity spectra, we have derived the optical conductivity and estimated the spectral weight up to various cut-off frequencies in underdoped BiSr$_2…
