Scaling of the superfluid density in high-temperature superconductors

C. C. Homes, S. V. Dordevic, T. Valla +1

A scaling relation ρ_s \simeq 35σ_{dc}T_c has been observed in the copper-oxide superconductors, where ρ_s is the strength of the superconducting condensate, T_c is the critical te…

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…

Coherence, incoherence and scaling along the c axis of YBa_2Cu_3O_{6+x}

C. C. Homes, S. V. Dordevic, D. A. Bonn +3

The optical properties of single crystals of YBa_2Cu_3O_{6+x} have been examined along the c axis above and below the critical temperature (T_c) for a wide range of oxygen dopings.…

The absence of superfluid response in ac and bc-plane optical conductivities of optimally-doped Bi2212 single crylstals in the surface region

J. J. Tu, C. C. Homes, L. H. Greene +2

The optical properties of optimally-doped Bi_2Sr_2CaCu_2O_{8+δ} (Bi2212) have been measured normal to the edge planes [ac plane, bc plane, and (1\bar{1}0) plane], for light polariz…

Sum rules and energy scales in the high-temperature superconductor YBa2Cu3O6+x

C. C. Homes, S. V. Dordevic, D. A. Bonn +2

The Ferrell-Glover-Tinkham (FGT) sum rule has been applied to the temperature dependence of the in-plane optical conductivity of optimally-doped YBa_2Cu_3O_{6.95} and underdoped YB…

Charge transfer in the high dielectric constant materials CaCu3Ti4O12 and CdCu3Ti4O12

C. C. Homes, T. Vogt, S. M. Shapiro +3

The cubic perovskite-related ceramic CaCu3Ti4O12 has a very high static dielectric constant ~10000 at room temperature (RT), which drops to about 100 below about 100 K. Substitutin…
