The n_s - T_c correlations in granular superconductors
Y. Imry, M. Strongin, C. C. Homes
Following a short discussion of the granular model for an inhomogeneous superconductor, we review the Uemura and Homes correlations and show how both follow in two limits of a simp…
An inhomogeneous Josephson phase in thin-film and High-Tc superconductors
Y. Imry, M. Strongin, C. C. Homes
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 region…
Extracting the electron--boson spectral function F() from infrared and photoemission data using inverse theory
S. V. Dordevic, C. C. Homes, J. J. Tu +5
We present a new method of extracting electron-boson spectral function F() from infrared and photoemission data. This procedure is based on inverse theory and will be shown…
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…
Universal scaling relation in high-temperature superconductors
C. C. Homes, S. V. Dordevic, M. Strongin +10
Scaling laws express a systematic and universal simplicity among complex systems in nature. For example, such laws are of enormous significance in biology. Scaling relations are al…
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…
Global trends in the interplane penetration depth of layered superconductors
S. V. Dordevic, E. J. Singley, D. N. Basov +5
We report on generic trends in the behavior of the interlayer penetration depth of several different classes of quasi two-dimensional superconductors including high-T cup…
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…
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…
