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…
Transient Infrared Photoreflectance Study of Superconducting MgB2: Evidence for Multiple Gaps and Interband Scattering
R. P. S. M. Lobo, J. J. Tu, Eun-Mi Choi +4
We studied the far-infrared reflectance of superconducting MgB2 in and out of equilibrium using pulsed synchrotron radiation. The equilibrium data can be described by a single ener…
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…
The mid-infrared AC Hall effect in optimally-doped BSCCO
D. C. Schmadel, J. J. Tu, L. B. Rigal +4
A novel heterodyne polarimetry system determines the frequency dependence from 900 to 1100 cm^-1 and temperature dependence from 35 to 330 K of the Hall transport in single crystal…
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…
