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…
Optical properties of (Pr,Ce)2CuO4
A. Zimmers, N. Bontemps, R. P. S. M. Lobo +5
We studied the optical conductivity of electron doped Pr{1-x)Ce(x)CuO(4) from the underdoped to the overdoped regime. The observation of low to high frequency spectral weight trans…
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…
Low temperature penetration depth and the effect of quasi-particle scattering measured by millimeter wave transmission in YBaCuO thin films
S. Djordjevic, L. A. de Vaulchier, N. Bontemps +7
Measurement of the penetration depth as a function of temperature using millimeter wave transmission in the range 130-500GHz are reported for three YBCO thin films. The experiment…
Onset of decoupling at the melting field of the vortex lattice in Bi2Sr2CaCu2O8 from microwave dissipation
H. Enriquez, Y. De Wilde, N. Bontemps +1
We have measured the microwave dissipation at 10 GHz in a Bi2Sr2CaCu2O8 single crystal, between 75 and 50 K, as a function of the static magnetic field applied parallel to the c ax…
