Sliding Density-Wave in Sr_{14}Cu_{24}O_{41} Ladder Compounds
G. Blumberg, P. Littlewood, A. Gozar +4
We used transport and Raman scattering measurements to identify the insulating state of self-doped spin 1/2 two-leg ladders of Sr_{14}Cu_{24}O_{41} as a weakly pinned, sliding dens…
Collective density wave excitations in two-leg Sr_{14-x}Ca_xCu_{24}O_{41} ladders
A. Gozar, G. Blumberg, P. B. Littlewood +4
Raman measurements in the 1.5 - 20 cm-1 energy range were performed on single crystals of Sr_{14-x}Ca_xCu_{24}O_{41}. A quasielastic scattering peak (QEP) which softens with coolin…
Reply to Comment on:"Nonmonotonic d_{x^2-y^2} Superconducting Order Parameter in Nd_{2-x}Ce_xCuO_4"
G. Blumberg, A. Koitzsch, A. Gozar +4
We confirm that all the results of scanning SQUID, tunneling, ARPES, penetration depth and Raman experiments are consistent with a nonmonotonic d_{x^2-y^2} superconducting order pa…
Nonmonotonic d_{x^2-y^2} Superconducting Order Parameter in Nd_{2-x}Ce_xCuO_4
G. Blumberg, A. Koitzsch, A. Gozar +4
Low energy polarized electronic Raman scattering of the electron doped superconductor Nd_1.85Ce_0.15CuO_4 (T_c=22 K) has revealed a nonmonotonic d_{x^2-y^2} superconducting order p…
