Suppression of Superfluid Density and the Pseudogap State in the Cuprates by Impurities
Unurbat Erdenemunkh, Brian Koopman, Ling Fu +5
We use scanning tunneling microscopy (STM) to study magnetic Fe impurities intentionally doped into the high-temperature superconductor BiSrCaCuO. Our spe…
Breakdown of the universal Josephson relation in spin ordered cuprate superconductors
A. A. Schafgans, C. C. Homes, G. D. Gu +3
We present \emph{c} axis infrared optical data on a number of Ba, Sr and Nd-doped cuprates of the LaCuO (La214) series in which we observe significant deviations from t…
Imaging nanoscale Fermi surface variations in an inhomogeneous superconductor
W. D. Wise, Kamalesh Chatterjee, M. C. Boyer +8
Particle-wave duality suggests we think of electrons as waves stretched across a sample, with wavevector k proportional to their momentum. Their arrangement in "k-space," and in pa…
Properties of charge density waves in LaBaCuO
Young-June Kim, G. D. Gu, T. Gog +1
We report a comprehensive x-ray scattering study of charge density wave (stripe) ordering in , for which the superconducting is greatly…
Magnetic field dependence of charge stripe order in La2-xBaxCuO4 (x~1/8)
Jungho Kim, A. Kagedan, G. D. Gu +4
We have carried out a detailed investigation of the magnetic field dependence of charge ordering in La2-xBaxCuO4 (x~1/8) utilizing high-resolution x-ray scattering. We find that th…
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…
