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…
An Inhomogeneous Josephson Phase Near the (Super) Conductor-Insulator Transition
Jiufeng Tu, M. Strongin, Y. Imry
In many cases inhomogeneities are known to exist near the metal (or superconductor)- insulator transition, as follows from well-known domain-wall arguments. If the conducting regio…
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…
Optical studies of charge dynamics in c-axis oriented superconducting MgB2 films
J. J. Tu, G. L. Carr, V. Perebeinos +7
Temperature dependent optical conductivities and DC resistivity of c-axis oriented superconducting (Tc = 39.6 K) MgB2 films (~ 450 nm) have been measured. The normal state ab-plane…
Charge dynamics and metal-insulator transition in SiGd and SiY alloys
D. N. Basov, A. M. Bratkovsky, P. F. Henning +5
Carrier dynamics in amorphous a-SiRE (RE=Gd, Y) films has been studied in the doping regime close to the metal-insulator transition by means of infrared spectroscopy.…
Optical studies of charge dynamics in the optimally-doped Bi2212 and the non-superconducting cobaltate single crystals
J. J. Tu, C. C. Homes, G. D. Gu +4
An analysis of the frequency-dependent scattering rate reveals signatures of the superconducting gap as well as the pseudogap in high-T_c cuprates. These features can be identified…
