The strange interplane conductivity of high-temperature superconductors

Andrew Millis

(Department of Physics and Astronomy, Rutgers University)

Abstract:  The  frequency and temperature dependence of the interplane conductivity of high-temperature superconductors has puzzled scientists for almost a decade, and has been argued to provide evidence in favor of an interlayer pairing mechanism for high-Tc superconductivity.  I will show that the anomalous features are straightforward consequences of the existence, in a certain temperature regime, of superconducting pairing without long ranged order, and will argue that the temperature and frequency dependence of the c-axis conductivity can be used to infer information about the strength of quantum fluctuations in the superconducting ground state.  This work is done in collaboration with L. B. Ioffe and supported by NSF-DMR-9707701.
